Lambda 8300
Template:Short descriptionTemplate:Infobox information appliance
The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong.[1][2][3] It had a modified ROM (including extra semigraphic characters) and extra hardware, making it not fully compatible.[4][5] Total compatibility could be achieved by installing a ZX81 ROM.[1]
It came with 2K RAM (expandable to 16K or 32K), three octave single voice sound (generated by a C4005 ULA I/O chip) and an Atari joystick port.[6] Specifically, it used a NEC D780C-1 (Z80A clone) microprocessor at 3.25 MHz.[1]
The character set was slightly altered from the ZX81, replacing some symbols with game graphics (see below).[3] BASIC tokens have alternate codings, further preventing 100% compatibility with the ZX81. Command input is done key by key (not by keyword entry like on the ZX81).[3]
The computer was somewhat successful in Northern Europe (mostly in Denmark and Norway) and China, and today enthusiasts still develop new hardware.Script error: No such module "Unsubst".
The Lambda 8300 can be emulated on modern systems using, for example, the EightyOne Sinclair Emulator[7][8] or MAME.[9]
Models
The machine was licensed to several different companies, with many rebranded models available in different markets.[1] Unisonic distributed it as the Futura 8300 in the US.[10][11] In France it was available as the DEF 3000.[12][13][14]

Character set
The character set was slightly altered from that of the ZX81, replacing the ,, ?, £, and ' symbols with game graphics: File:Lambda 8300 symbol 3.png, File:Lambda 8300 symbol 2.png, File:Lambda 8300 symbol 1.png and File:Lambda 8300 symbol 0.png.[3] BASIC tokens also have alternate codings.[3]
