The Timex Sinclair 1000 (TS1000) was the first computer produced by Timex Sinclair, a joint-venture between Timex Corporation and Sinclair Research. It was launched in July 1982.
The TS1000 was a slightly modified Sinclair ZX81 with an NTSC RF modulator instead of a UK PAL (Units sold in Portugal have a PAL RF modulator) device and the onboard RAM doubled to two KBs. The TS1000’s casing had slightly more internal shielding but remained the same as Sinclair’s, including the membrane keyboard. It had black & white graphics, and no sound. It was followed by an improved version, the Timex Sinclair 1500.
Like the Sinclair ZX81, the TS1000 used a form of BASIC as its primary interface and programming language. To make the membrane keyboard less cumbersome for program entry, the TS1000 used a shortcut system of one-letter “keywords” for most commands (i.e. pressing Shift-”P” would generate the keyword “PRINT”). Some keywords required a short sequence of keystrokes (e.g. SHIFT-ENTER S would generate the keyword “LPRINT”). The TS1000 clued the user in on what to expect by changing the cursor to reflect the current input mode. (From Wikipedia, the free encyclopedia)
