The '''Power Macintosh G3''' (also sold with additional software as the '''Macintosh Server G3''') is a series of [[personal computer]]s designed, manufactured, and sold by [[Apple Inc.|Apple Computer]] from November 1997 to August 1999. It represented Apple's first step towards eliminating redundancy and complexity in the product line by replacing eight [[Power Macintosh]] models (and the [[Twentieth Anniversary Macintosh]]) with three: Desktop and Mini Tower models for professional and home use, and an [[All-in-one computer|all-in-one]] model for education. The introduction of the Desktop and Mini Tower models coincided with Apple starting to sell build-to-order Macs directly from its web site in an online store,<ref>{{Cite web |title=Apple Store online turns 10 years old |url=http://www.macworld.co.uk/business/news/index.cfm?RSS&NewsID=19652 |url-status=dead |archive-url=https://web.archive.org/web/20100105005854/http://www.macworld.co.uk/business/news/index.cfm?RSS |archive-date=January 5, 2010 |df=mdy-all}}</ref><ref>{{Cite web |title=Apple Computer |url=https://www.apple.com/ |url-status=deviated |archive-url=https://web.archive.org/web/19980509035420/http://www.apple.com/ |archive-date=May 9, 1998 |access-date=2009-01-17 |df=mdy-all}}</ref> which was unusual for the time as [[Dell]] was the only major computer manufacturer doing this. Apple's move to build-to-order sales of the Power Macintosh G3 also coincided with the acquisition of [[Power Computing Corporation]], which had been providing telephone sales of [[Macintosh clone]]s for more than two years.

The Power Macintosh G3 is named for its [[PowerPC 7xx#PowerPC 740/750|third-generation PowerPC chip]], and introduced a super fast and large Level 2 backside [[CPU cache]], running at half processor speed. As a result, these machines [[Benchmark (computing)|benchmarked]] significantly faster than [[Intel]] PCs of similar CPU clock speed at launch,<ref>{{Cite web |last=Mesa |first=Andy |year=1998 |title=Power Macintosh G3 |url=http://applemuseum.bott.org/sections/computers/G3.html |url-status=live |archive-url=https://web.archive.org/web/20110718175003/http://applemuseum.bott.org/sections/computers/G3.html |archive-date=July 18, 2011 |access-date=August 8, 2006 |publisher=The Apple Museum}}</ref> which prompted Apple to create the "Snail" and "Toasted Bunnies" television commercials.<ref>{{Cite web |title=Snail and Toasted Bunnies |url=https://www.apple.com/hotnews/features/ads/ |url-status=dead |archive-url=https://web.archive.org/web/19980429154639/http://www.apple.com/hotnews/features/ads/ |archive-date=April 29, 1998 |access-date=2006-08-08 |df=mdy-all}}</ref><ref>[http://lowendmac.com/musings/pentiumii.shtml PowerPC vs. Pentium II: Escargot?] {{Webarchive|url=https://web.archive.org/web/20111107175830/http://lowendmac.com/musings/pentiumii.shtml |date=November 7, 2011 }} Retrieved February 6, 1998.</ref><ref>{{YouTube|AZZ-LPbQRy0|Apple Launches New "Snail" Commercial}}</ref><ref>Archived at [https://ghostarchive.org/varchive/youtube/20211211/-FlfZ9BI9lM Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20140704222107/http://www.youtube.com/watch?v=-FlfZ9BI9lM Wayback Machine]{{cbignore}}: {{Citation |last=AI Perspectives |title=Apple Unveils "Toasted Bunny" Commercial |date=2009-08-05 |url=https://www.youtube.com/watch?v=-FlfZ9BI9lM |access-date=2016-10-09}}{{cbignore}}</ref> Magazine benchmarks showed the G3/266 CPU outperforming the 350&nbsp;MHz [[PowerPC 604ev]] chip in the [[Power Macintosh 9600]] as well.<ref>{{Cite web |last=Tafel |first=Kathy |date=January 1998 |title=Power Macintosh G3 Kicks Ass |url=https://archive.org/stream/MacAddict-017-199801/MacAddict-017-199801-BobKiwi-v1#page/n43/mode/2up/search/42 |publisher=MacAddict |page=42}}</ref>

Two generations of the Power Macintosh G3 were released. The first generation, known colloquially as "Beige"<ref>{{Cite web |date=November 16, 1997 |title=Beige Power Mac G3 (1997) |url=http://lowendmac.com/1997/beige-power-mac-g3-1997/ |url-status=live |archive-url=https://web.archive.org/web/20170908063836/http://lowendmac.com/1997/beige-power-mac-g3-1997/ |archive-date=September 8, 2017 |access-date=September 8, 2017 |publisher=Low End Mac}}</ref> was introduced at a special event on November 10, 1997. The second generation, known officially as "Blue and White", was introduced at MacWorld San Francisco on January 5, 1999. Its replacement, the [[Power Mac G4]], was introduced in August of the same year.

== Models ==
=== Beige ===
[[File:Macintosh G3 DT.jpg|Power Macintosh G3 Desktop|thumb|180px]]
Apple sold three beige Power Macintosh G3 models: a horizontally-oriented desktop, a mini tower enclosure, and a version with a built-in screen called All-In-One ("AIO"). The All-In-One model was shaped vaguely like a human tooth, and thus earned the moniker '''Molar Mac.'''<ref name="All-in-One"/> Equipped with a 233, 266, 300, or 333&nbsp;MHz PowerPC 750 (G3) CPU from [[Motorola]], these machines use a 66.83&nbsp;MHz system bus and [[PC66]] [[Synchronous dynamic random-access memory|SDRAM]], and standard ATA [[hard disk]] drives instead of the [[SCSI]] drives used in most previous Apple systems. A Fast SCSI internal bus is still included with 10&nbsp;MB/s speed,<ref>1 MB = 1 million bytes</ref> along with the proprietary out-of-spec DB-25 external SCSI bus which had a top speed of 5&nbsp;MB/s.<ref name="g3mini333specs"/> Each bus could support a maximum of 7 devices.

Apple also developed a prototype G3-based six-slot full tower to be designated the '''Power Macintosh 9700'''.<ref>{{Cite web |title=Apple Macintosh PowerExpress (prototype) |url=http://www.digibarn.com/collections/systems/mac-powerexpress/ |url-status=live |archive-url=https://web.archive.org/web/20170701023028/http://www.digibarn.com/collections/systems/mac-powerexpress/ |archive-date=July 1, 2017 |access-date=September 4, 2017}}</ref> Despite demand from high-end users for more PCI slots in a G3-powered computer, Apple decided not to develop the prototype (dubbed "Power Express") into a shipping product,<ref>{{Cite web |title=The Apple Museum {{!}} Prototypes / Unreleased<!-- Bot generated title --> |url=http://www.theapplemuseum.com/index.php?id=31 |url-status=live |archive-url=https://web.archive.org/web/20070811023642/http://www.theapplemuseum.com/index.php?id=31 |archive-date=August 11, 2007 |access-date=April 18, 2007}}</ref> leaving the [[Power Macintosh 9600|9600]] as the last six-slot Mac Apple would make for over two decades, until the [[Mac Pro|2019 Mac Pro]] which has eight.

Initial units were shipped with [[Mac OS 8]]. The G3 officially supports up to [[Mac OS X 10.2]], although some devices will not work under Mac OS X, such as the floppy drive, the video features of the "Wings" personality card, and the [[3D computer graphics|3D graphics]] acceleration functions of the onboard ATI Rage series video. Support for newer versions is possible with the use of third-party software solutions such as [[XPostFacto]]. [[Mac OS X 10.5]] can be run only if a G4 processor upgrade is installed.

The Power Macintosh G3 was originally intended to be a midrange series, between the low-end [[Macintosh Performa|Performa]]/[[Macintosh LC|LC]] models and the six-[[PCI slot]] [[Power Macintosh 9600]]. It is the earliest [[Old World ROM]] Macintosh model officially able to boot into [[macOS|Mac OS X]], and one of only two Old World ROM models officially able to boot into Mac OS X, the other model being the second-generation (Wallstreet I/II) [[PowerBook G3]].

==== Desktop ====
The Desktop model inherited its enclosure directly from the [[Power Macintosh 7300]]. The 233 and 266&nbsp;MHz desktop models shipped with 4&nbsp;GB hard drives,<ref>1 GB = 1 billion bytes</ref> and the 300&nbsp;MHz with a 6&nbsp;GB drive, all at 5400&nbsp;RPM. This model, sometimes referred to as an [[Outrigger Macintosh]] due to its ease of access, was the last horizontally-oriented desktop model offered by Apple until the introduction of the [[Mac mini]] in 2005.

The Desktop model received an update in August 1998,<ref>{{Cite web |title=Power Macs hit 366 |url=https://www.zdnet.com/article/power-macs-hit-366/ |url-status=live |archive-url=https://web.archive.org/web/20201024184742/https://www.zdnet.com/article/power-macs-hit-366/ |archive-date=October 24, 2020 |access-date=September 4, 2017 |website=[[ZDNet]]}}</ref> with the 233&nbsp;MHz model being discontinued. Unlike the Mini Tower model, the Desktop model was not updated with 333&nbsp;MHz or 366&nbsp;MHz CPUs. Regardless, it was replaced by the [[Power Mac G4 Cube]] in 2000.

==== Mini Tower ====
The 233&nbsp;MHz Mini Tower model's enclosure is similar to the [[Power Macintosh 8600]]. It shipped with a 4&nbsp;GB drive, the 266&nbsp;MHz with a 6&nbsp;GB drive, and the 300&nbsp;MHz variant shipped with two 4&nbsp;GB drives in a [[RAID]] configuration; all models were 5400&nbsp;RPM.

As with the Desktop model, the Mini Tower received an update in August 1998,<ref name="g3mini333specs">{{Cite web |title=Apple Power Macintosh G3 333 Minitower Specs |url=http://www.everymac.com/systems/apple/powermac_g3/specs/powermac_g3_333_mt.html |url-status=live |archive-url=https://web.archive.org/web/20170905002551/http://www.everymac.com/systems/apple/powermac_g3/specs/powermac_g3_333_mt.html |archive-date=September 5, 2017 |access-date=September 4, 2017 |publisher=EveryMac}}</ref> with the CPU updated to 333&nbsp;MHz and 366&nbsp;MHz. These models shipped with a 9.1&nbsp;GB 7200 RPM SCSI drive, attached to a SCSI/PCI card, as well as [[100BASE-TX]] Ethernet (as opposed to the other models' [[10BASE-T]]), though this was in the form of a PCI card, which occupied another PCI slot. The Macintosh Server G3/300&nbsp;MHz also shipped with a PCI Ultra Wide SCSI card and the 100BASE-T Ethernet PCI card. The 333 and the (canceled) 366&nbsp;MHz model had only 6&nbsp;[[mebibyte|MiB]] VRAM;<ref>1 MiB = 1024<sup>2</sup> B</ref> the 300&nbsp;MHz model shipped with a 128-bit [[iXMicro]] PCI video card with 8&nbsp;MiB VRAM.

==== Server ====
The Macintosh Server G3 is identical to the Mini Tower model, but was sold with additional server software and different specifications.<ref>{{Cite web |title=Macintosh Server G3 |url=https://www.apple.com:80/powermac/g3/server/ |url-status=dead |archive-url=https://web.archive.org/web/19980509040720/http://www.apple.com/powermac/g3/server/ |archive-date=May 9, 1998 |publisher=Apple |df=mdy-all}}</ref> Software included [[AppleShare]] IP 5.0, Apple Network Administrator Toolkit, and SoftRAID.

==== All-In-One ====
[[File:Power Mac G3 AIO corrected.jpg|Power Macintosh G3 All-In-One|thumb|150px]]
The All-In-One model was introduced in April 1998 as a replacement for the [[Power Macintosh 5400]] and [[Power Macintosh 5500|5500]],<ref name="MiniTower"/> and sold exclusively to the education market. The All-In-One model has a "[[Molar (tooth)|molar]]"-like form factor, with its top and rear sections covered in a translucent plastic with machined holes (a design language reminiscent of the then-upcoming [[IMac G3|iMac]]). The model has several design features oriented towards the education market, including a slide-out tray for accessing the logic board, recessed rear I/O to make it easier to push the computer up against walls, and dual front headphone jacks for audio sharing.<ref name=":0">{{Cite magazine |last=Tafel |first=Kathy |date=June 1998 |title=All Things To All People |url=https://archive.org/stream/MacAddict-022-199806/MacAddict-022-199806-BobKiwi-v1#page/n27/mode/2up |magazine=MacAddict |page=27}}</ref><ref name=":1">{{Cite web |title=Molar Mac: The Fast, Heavy, Beauty Challenged AIO |url=https://www.wap.org/journal/molarmac/ |url-status=live |archive-url=https://web.archive.org/web/20170905002013/https://www.wap.org/journal/molarmac/ |archive-date=September 5, 2017 |access-date=2022-04-28 |website=Washington Apple Pi}}</ref>

The G3 AIO was available in two basic configurations, a 233&nbsp;MHz version with a floppy drive and a 4&nbsp;GB hard drive, and a 266&nbsp;MHz version with a built-in [[Zip drive]], floppy drive, and either a "Whisper" personality card or an All-In-One version of the "Wings" personality card. It was the last Macintosh to ship with an internal floppy disk drive. The machine is also noted for its considerable {{Cvt|60|lb}} weight.<ref name=":1"/><ref name=":0"/> It shipped with [[Mac OS 8.1]].<ref name=":0"/>

When the iMac G3 was introduced, the G3 AIO and iMac were sold together to the education market until the G3 AIO was discontinued.<ref>Archived at [https://ghostarchive.org/varchive/youtube/20211211/_oR9evVAaX8 Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20211108151457/https://www.youtube.com/watch?v=_oR9evVAaX8 Wayback Machine]{{cbignore}}: {{Citation |title=Apple Confidential iMac G3 vs PowerMac G3 AIO 1998 372226305 |url=https://www.youtube.com/watch?v=_oR9evVAaX8 |access-date=2021-11-08 |language=en}}{{cbignore}}</ref>

=== Blue and White ===
[[File:Apple Yosemite.JPG|thumb|150px|Side view of Power Macintosh G3 (Blue and White)]]
The '''Power Mac G3 (Blue and White)'''<!-- (Not "Blue & White"; see Apple's spec sheets for confirmation) --> (codenamed Yosemite) was introduced in January 1999, replacing the Beige Mini Tower model, with which it shared the name and processor architecture but little else. It is the first Power Macintosh model to include the [[New World ROM]], and the last with [[Apple Desktop Bus|ADB]] port. {{nowrap|300 MHz}}, {{nowrap|350 MHz}} and {{nowrap|400 MHz}} models were introduced with a price range of US$1,599 – US$2,999.<ref name="macworldg3bw">{{Cite magazine |last=Breen |first=Christopher |date=April 1999 |title=Power Mac G3 – Desktop Macs' Enhancements Are More Than Skin Deep |url=https://archive.org/stream/MacWorld_9904_April_1999#page/n33/mode/2up |magazine=MacWorld |pages=32–33}}</ref>

Though still based on the [[PowerPC 7xx|PowerPC G3]] architecture, the Blue and White was a totally new design. It was the first new Power Mac model after the release of the [[iMac]], and shared the iMac's blue-and-white color scheme. Inside the enclosure, the logic board is mounted on a folding "door", which swings down onto the desk for tool-free access to all the internal components.<ref name="macworldg3bw"/>

The same keyboard and mouse designs as those first introduced with the iMac were sold with the system. These featured the same slightly different shade of blue from that of the Bondi Blue iMac to match the new G3 enclosure. The keyboard was criticized in MacWorld's review of the G3 as feeling "cheap compared with the huge Apple keyboard of old" and the removal of several keys. The [[Hockey puck mouse|Apple USB Mouse]], previously included with the [[iMac]], was also reviewed poorly, noting that "many users will find it unacceptable: because of the round design, it's impossible to tell the top of the mouse from the bottom by touch."<ref name="macworldg3bw"/>

The Blue and White line was revised in June 1999; the {{nowrap|300 MHz}} model was dropped and a new {{nowrap|450 MHz}} model was introduced at a US$2,999 price point.<ref>{{Cite web |title=Apple Power Macintosh G3 450 (Blue & White) Specs |url=http://www.everymac.com/systems/apple/powermac_g3/specs/powermac_g3_450_bl.html |url-status=live |archive-url=https://web.archive.org/web/20170831131535/http://www.everymac.com/systems/apple/powermac_g3/specs/powermac_g3_450_bl.html |archive-date=August 31, 2017 |access-date=September 10, 2017 |publisher=EveryMac}}</ref>

Early Blue and White units shipped with [[Mac OS 8]].5.1, while later revisions shipped with 8.6. The latest version of Mac OS that can be run on this model is [[Mac OS X 10.4]] Tiger.

[[File:PIC 0836 Power Macintosh G3.JPG|A partially opened G3 minitower|thumb]]

==== Logic board ====
The Beige G3 uses Apple's new "Gossamer" logic board. As a compact and versatile motherboard, the Gossamer board was originally designed to be able to support both the high-end PowerPC 604e and the new PowerPC G3, but when initial testing found that the cheaper G3 outperformed the 604e in many benchmarks, this functionality was removed and Apple's 604e-based systems were discontinued.

Gossamer supports both onboard and external SCSI (from the custom [[Macintosh Enhanced SCSI Hardware|MESH]] [[Integrated circuit|IC]]), [[Apple Desktop Bus|ADB]], 10BASE-T [[Ethernet]], two [[Mini-DIN connector|MiniDIN]]-8 serial ports, and onboard [[ATI Technologies|ATI]] graphics (originally [[ATI Rage#3D RAGE II (IIC, II+, II+DVD)Rage|II+]], later updated to [[ATI Rage#3D RAGE ProRage|Pro and then Rage Pro Turbo]]) with a slot for [[Video RAM|VRAM]] upgrades. An external serial port is included; this is the last Power Macintosh model to include one. Three 32-bit PCI slots and one internal [[modem]] slot are present, as well as three SDRAM slots.

==== ROM ====
Early G3s with Revision A ROMs do not support slave devices on their [[Advanced Technology Attachment|IDE]] controllers, limiting them to one device per bus (normally one optical drive and one hard disk). Additionally, they came with onboard [[ATI Rage]] II+ video. G3s with Revision B ROMs support slave devices on their IDE controllers, and had the onboard video upgraded to ATI Rage Pro. G3s with Revision C ROMs also support slave devices on their IDE controllers, but the most significant technical differences are the newer [[Open Firmware]] version than the previous two models (2.4 vs 2.0f1) and another onboard video upgrade, this time to ATI Rage Pro Turbo.

The Beige G3 was the last Power Macintosh with a 4&nbsp;MiB ROM. The trend of increasingly large ROMs ended after the introduction of the [[New World ROM]] in the Blue and White G3.

==== Personality cards ====
These machines had no audio circuitry on the logic board; instead, a PERCH slot (a dedicated 182-pin microchannel connector; a superset of the PCI spec, but which does not accept PCI cards) was populated with a "personality card" which provided the audio circuitry. Several "personality cards" were available:<ref>{{Cite web |title=Apple G3 Beige Perch Cards |url=http://www.forevermac.com/1997/08/apple-power-macintosh-g3-266-minitower#G3_Personality |url-status=live |archive-url=https://web.archive.org/web/20120926003053/http://www.forevermac.com/1997/08/apple-power-macintosh-g3-266-minitower/#G3_Personality |archive-date=September 26, 2012 |access-date=September 16, 2012}}</ref>
* '''Whisper''' was the personality card of the regular versions, providing the Screamer sound [[Application-specific integrated circuit|ASIC]] (with 16-bit, 44.1&nbsp;kHz audio capabilities with simultaneous I/O) and no video facilities.
* '''Wings''' or ''Audio/Video Input/Output Card'' was an A/V "personality card" which, in addition to the audio I/O, included [[Composite video|composite]] and [[S-Video]] capture and output.
* '''Bordeaux''' or ''DVD-Video and Audio/Video Card'' differed from the Wings card in that it did not include a DAV slot, used the Burgundy sound [[Application-specific integrated circuit|ASIC]] (which provided improved sound performance), incorporated a higher performance video capture IC, and included additional circuitry (C-Cube MPEG decoder chip) to support the playback of [[DVD-Video|DVD]] movies. The All-In-One does not support the Bordeaux card, as it lacks the connectors for the AIO's front panel and [[RGB color model|RGB]] video cables.<ref>{{Cite web |date=August 13, 1998 |title=Developer Note: Power Macintosh G3 Computers |url=http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G3/PowerMac_G3/PowerMac_G3.pdf |url-status=dead |archive-url=https://web.archive.org/web/20071128060807/http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G3/PowerMac_G3/PowerMac_G3.pdf |archive-date=November 28, 2007 |access-date=March 22, 2019 |publisher=Apple Computer, Inc.}}</ref>

==== Upgradability ====
'''CPU''': The processor module (a [[PowerPC G3#PowerPC 740/750|PowerPC 750]] plus L2 cache) was overclockable, i.e. 333&nbsp;MHz and even 366&nbsp;MHz or 375&nbsp;MHz with an 83.3&nbsp;MHz bus (uncommon).<ref>{{Cite web |date=November 17, 1997 |title=Clocking the Power Mac G3 |url=http://lowendmac.com/ppc/j16.shtml |url-status=live |archive-url=https://web.archive.org/web/20061016005333/http://lowendmac.com/ppc/j16.shtml |archive-date=October 16, 2006 |access-date=September 9, 2006}}</ref> Upgrade kits were available from a number of companies, including Newer Technology, PowerLogix and XLR8, offering {{nowrap|400 MHz}} G3 processors in the US$1,500 – US$1,800 price range.<ref>{{Citation |title=MacWorld February 1999 |url=https://archive.org/stream/MacWorld_9902_February_1999#page/n29/mode/2up |pages=27–28 |year=1999 |publisher=MacWorld}}</ref>
CPU upgrades as high as a 1.0&nbsp;GHz G4 or 1.1&nbsp;GHz G3 would eventually become available, although the user would not see much practical difference in performance on chips faster than 733&nbsp;MHz due to the system bus limitations, which runs at 66.83&nbsp;MHz unless overclocked. However, G4 chips running over 533&nbsp;MHz do not allow the system bus to run faster than 66&nbsp;MHz, so the bus cannot be overclocked if using one of these G4s. (G3s do allow it.)

'''PCI cards''': Gossamer has three full-length (12") PCI slots, making it capable of taking any PCI cards that have Macintosh drivers available for them (for example, some RealTek-based network adapters, a lot of USB, ATA/IDE [or SATA] and FireWire cards). Common PCI card upgrades include [[FireWire]] cards, [[Universal Serial Bus|USB]] cards and FireWire/USB combo cards (especially after the release of the first generation iMac, which caused many vendors to start releasing USB peripherals for the Macintosh), 100BASE-TX or 1000BASE-T ([[gigabit Ethernet]]) network adapter, video cards (e.g. ATI Radeon 7000 and 9200), ATA/EIDE, [[Serial ATA]] and Ultra SCSI cards. Television tuner and radio cards are also often chosen to supplement the AV features on a Wings personality card, or to provide A/V input for models with the Whisper personality card. The All-In-One can be modified to use a PCI video card with the internal monitor.<ref>{{Cite web |last=Curd |first=Shane |title=Adding a PCI Video Card to an Apple Macintosh G3 AIO |url=http://www.shanecurd.com/wordpress/?p=220 |url-status=dead |archive-url=https://web.archive.org/web/20120925073608/http://www.shanecurd.com/wordpress/?p=220 |archive-date=September 25, 2012 |access-date=March 1, 2009}}</ref>

'''Personality cards''': Some users have upgraded the Whisper personality card with a "Wings" Personality card (which is plugged into the same PERCH slot), and some have upgraded the [[Read-only memory|ROM]] to a newer version (Revision A boards to Revision B or Revision C boards).

'''Hard drives''': For storage, the G3 is capable of taking any ATAPI/IDE hard disks, provided that the drive's size is within the 28-bit LBA limit. This means ATA hard disks of up to 137&nbsp;[[Gigabyte|GB]] (2<sup>28</sup> blocks of 512 bytes each) are supported. This limitation can be overcome by using an IDE or SATA PCI-compatible card (e.g. Acard or Sonnet) to enable the use of 2 drives over the 137&nbsp;GB limit.

'''Removable storage''': The ATAPI/IDE CD-ROM drive can also be replaced with a CD-RW, DVD-ROM or DVD-RW drive, although care must be taken while purchasing the upgrade as the Mac is incompatible with some drives and may refuse to boot at all if an incompatible drive is installed. Also, many third-party optical drives cannot be used as boot devices with the G3, though they work correctly for normal use, and burning on many third party CD-RW and DVD-RW drives requires either commercial drivers or is unsupported even though reading and booting from the drive may still work. It is also capable of taking SCSI storage devices, and with the presence of the right PCI cards, SATA, USB and FireWire storage devices.

'''SCSI''': The presence of an onboard SCSI controller (the SCSI controller is codenamed MESH — '''M'''acintosh '''E'''nhanced '''S'''CSI '''H'''ardware) and connectors permits the use of Mac-enabled SCSI scanners and storage devices, though this runs at only 5&nbsp;MB/s.

'''Memory''': Apple's spec sheets specify a maximum memory limit of {{nowrap|192 MiB}}, but independent testers have reported being able to use {{nowrap|3x256 MiB}} SDRAM chips, for a total of {{nowrap|768 MiB}}.<ref>{{Cite web |title=Power Mac G3 Desktop (Gossamer) |url=https://www.macgurus.com/products/motherboards/mbppcg3desk.php |url-status=live |archive-url=https://web.archive.org/web/20170912102434/https://www.macgurus.com/products/motherboards/mbppcg3desk.php |archive-date=September 12, 2017 |access-date=September 12, 2017 |publisher=MacGurus}}</ref> Incompatibility has been reported with some DIMM modules in certain configurations- for example, newer single-sided PC‑133 RAM modules will not be detected correctly if they will be detected at all and if the machine can boot with them in place, and the desktop and all-in-one units required the use of low-profile RAM due to space constraints. It should be able to take 168-pin SDRAM of any speed, though it will run at PC66 speeds. The onboard video RAM can be upgraded from 2&nbsp;MiB to 6&nbsp;MiB with a 4&nbsp;MiB SGRAM module (which runs at 83&nbsp;MHz on Rev. A machines, and 100&nbsp;MHz on Rev. B and C machines).

=== Blue and White ===
[[File:1Open Power MacG3.JPG|thumb|The inside of the Power Mac G3 (Blue and White)]]
The faster models (not the 300&nbsp;MHz model) use the new [[Copper-based chips|copper-based]] PowerPC G3 CPUs made by [[IBM]], which use about 25% of the power of the Motorola versions clock for clock. The line ranged from 300 to 450&nbsp;MHz. Despite its 100&nbsp;MHz system bus and PC100 SDRAM, the 300&nbsp;MHz B&W G3 performed worse than its 300&nbsp;MHz Beige predecessor, because it has 512&nbsp;KiB L2 cache, half of the 300&nbsp;MHz Beige.<ref name="macworldg3bw"/> The logic board has 4 PCI slots: 3 64-bit 33&nbsp;MHz slots, and one 32-bit 66&nbsp;MHz slot dedicated for the graphics card, an ATI Rage 128 with 16&nbsp;MiB [[Dynamic random access memory|SGRAM]]. Four 100&nbsp;MHz RAM slots accept PC100 SDRAM modules, allowing the installation of up to 1&nbsp;GiB of RAM with the use of 256&nbsp;MiB DIMMs. The onboard ATA was upgraded to Ultra [[Advanced Technology Attachment|ATA/33]] (an extra UDMA-33 controller was also added), but SCSI was no longer present, having been replaced by 2 FireWire ports, a new standard (IEEE1394) running at 400&nbsp;[[Megabit per second|Mbit/s]] (50&nbsp;[[Megabyte per second|MB/s]]<!-- mentioning this way because we are about to contrast with the ATA/33 data rate -->) — faster in theory than even the ATA/33 (33&nbsp;MB/s) hard drive controller. The [[serial port]]s were replaced with [[Universal Serial Bus|USB]] 1.1 ports (12&nbsp;Mbit/s), and the floppy disk drive was removed altogether. The [[Apple Desktop Bus|ADB]] port remained, as did the option for an internal modem. 100BASE-TX Ethernet became standard, and audio was moved back to the logic board. A Zip Drive remained an option, and some configurations included a [[DVD-ROM]] drive and a DVD-Video decoder [[Daughterboard|daughtercard]] for the graphics card, allowing hardware-assisted DVD video playback.

The Blue and White G3 uses a modified version of the memory/PCI controller, the Motorola MPC106 (codenamed "Grackle"); it used the MPC106 v4. The I/O "Heathrow" had been replaced by "Paddington" (adding 100 Mbit Ethernet and power save features), the audio chip "Screamer" (on the beige G3's "Whisper" and "Wings" personality cards) had been replaced by "Burgundy" (from the "Bordeaux" personality card), and other controllers for Firewire (Texas Instruments PCI-Lynx), for USB etc. were added.

This is also the first Power Macintosh with the "New World" architecture which contained a small (approximately 1&nbsp;MB) boot ROM. When booting the Mac OS, the Mac OS Toolbox and any other ROM patches installed are loaded into RAM (the former Beige G3 however was the first Mac with this ROM-in-RAM capability). Initially, many buyers chose to buy the older "Platinum" G3s instead, in order to maintain compatibility with existing peripherals.

Early "Revision 1" units have IDE controller problems related to the ATA/33 hard drive controller that made it impossible to connect two hard drives and prevented the use of newer drives. Using newer ATA drives in those units resulted in data transmission errors if the drives were connected to the on-board ATA/33 controller, the severity of the problem varying according to the particular make and model of the drive. Workarounds include replacing motherboards and employing the use of SCSI, Ultra ATA or SATA PCI controller cards. Stable operation can be achieved if the drive can be limited to Multi-Word DMA Mode 2 (disabling UDMA), although this limits throughput to 16&nbsp;MB/s. Some hard drives support disabling UDMA in firmware through manufacturer-supplied utilities (generally DOS-based). Alternatively, the transfer mode can be limited to Multi-Word DMA Mode 2 through the use of third-party driver software such as FWB Hard Disk Toolkit.

The secondary [[ATA channel]] has also been reported to have issues with respect to flash upgrading certain DVD burners. Otherwise, it is generally held to be relatively stable.

Mac OS X attempts to avoid the UDMA issue by disabling UDMA on all affected G3 motherboards, but xlr8yourmac.com reported that reader Tim Seufert still found issues with single drives under Mac OS X. He reported that as of January 23, 2002, the fix would not be activated under Mac OS X when no slave drive was present.<ref>{{Cite web |title=Accelerate Your Mac FAQ: Apple G3 Systems Specific Topics |url=http://forums.xlr8yourmac.com/action.lasso?-database=faq.fp3&-layout=FaqList&-response=answer.faq.lasso&-recordID=33781&-search |url-status=dead |archive-url=https://archive.today/20120711060629/http://forums.xlr8yourmac.com/action.lasso?-database=faq.fp3&-layout=FaqList&-response=answer.faq.lasso&-recordID=33781&-search |archive-date=July 11, 2012 |access-date=2008-10-17 |df=mdy-all}}</ref>

The "Revision 2" units fixed the hard drive controller problem with an improved (UDMA-33) IDE controller that supported the standard IDE master/slave two-drive arrangement. This controller worked flawlessly with any drive within the 28-bit LBA constraint. Most Rev. 2 units shipped with a hard disk bracket designed for two drives (in fact Rev. 1 can hold up to three drives side-by-side, while Rev. 2 can hold up to four drives in two stacks, each with two drives) and also included a slightly updated version of the Rage 128 graphics card. The easiest way to tell if the unit is a Rev.2 is by looking at the CMD chip located on the logic board. The CMD chip on Rev. 1 logic boards is PCI646U2 and on Rev. 2 logic boards is 646U2-402.<ref>{{Cite web |title=Power Mac G3 Blue & White Rev 2 Logic Board |url=http://www.welovemacs.com/6612194.html |url-status=live |archive-url=https://web.archive.org/web/20100224230910/http://welovemacs.com/6612194.html |archive-date=February 24, 2010 |access-date=March 25, 2010 |publisher=Welovemacs.com}}</ref>

Revision 2 350, 400, and 450&nbsp;MHz units use the same motherboard as the first "Yikes" version of [[Power Mac G4]] systems at 350 and 400&nbsp;MHz ("Sawtooth" AGP-based G4s used a different board) and processor cards for these models are interchangeable. Note that if a G3's firmware has been upgraded (a required update for installing Mac OS 9), it won't accept G4 CPUs until patched with a third-party replacement firmware. A Blue and White G3 that has been upgraded to a G4 is able to run [[Mac OS X 10.5]] Leopard.

==== Enclosure ====
The blue and white G3's enclosure design was widely praised at the time for being easy to open up and work on.<ref>{{Cite web |title=Power Mac G3 (Blue and White) |url=http://www.insanely-great.com/reviews/b&wg3.html |archive-url=https://web.archive.org/web/20080330001622/http://www.insanely-great.com/reviews/b%26wg3.html |archive-date=March 30, 2008 |website=www.insanely-great.com}}</ref> The entire right side of the case is a door that hinges down by pulling a recessed latch at the top. No components need to be removed or unplugged, and the computer can remain running while opened. The [[logic board]] is positioned in the door, providing access to all components. Hard drives are mounted in a bracket affixed with one screw on the floor of the case. There is room for four internal hard drives and an internal fan is positioned at the side of the case to blow cooling air over them. Removable drives are in a more conventional position at the top of the case.
