The '''Ultra 1''' is a family of [[Sun Microsystems]] [[workstation]]s based on the [[64-bit]] [[UltraSPARC]] [[microprocessor]]. It was the first model in the [[Sun Ultra series|Ultra series]] of Sun computers, which succeeded the [[SPARCstation]] series. It launched in November 1995 alongside the MP-capable '''Ultra 2''' and shipped with [[Solaris (operating system)|Solaris]] 2.5. It is capable of running other operating systems such as [[Linux]] and [[BSD]].

==Specifications==
The Ultra 1 was available in a variety of specifications. The Ultra 1 Creator3D 170E launched with a list price of {{USD|27995|1995|round=-2}} - along with the Ultra 1 Model 140, and Ultra 1 Creator 170E.<ref>{{cite web

===CPU===
Three different CPU speeds were available: 143 MHz (Model 140), 167 MHz (Model 170) and 200 MHz (Model 200). 
===Models===
Model numbers with an ''E'' suffix (Sun service code A12, code-named ''Electron'') had two instead of three [[SBus]] slots, and added a [[Ultra Port Architecture|UPA]] slot to allow the use of an optional [[Creator (framebuffer)|Creator]] [[framebuffer]]. In addition, the E models had [[Wide SCSI]] and [[Fast Ethernet]] interfaces, in place of the narrow SCSI and [[10BASE-T]] Ethernet of the standard Ultra 1 (service code A11, code-named ''Neutron'').  

===Memory===
The Ultra 1 uses 200-pin 5V ECC 60 ns [[SIMM]]s in pairs, the same memory used in the [[SPARCstation 20]].

==Similar Machines==
Similar Sun machines were the Netra i 1 servers which had the same chassis [http://sunsolve.sun.com/handbook_pub/Systems/Ultra_1E/Ultra_1_140E_170E_200E.html] and the UltraServer 1/[[Ultra Enterprise]] 1 servers [http://sunsolve.sun.com/search/document.do?assetkey=1-25-19521-1].
