Timex Sinclair 1500

Computers · Timex Corporation

Timex's second ZX81-derived US machine — same core, a roomier case, and 16 KB of RAM built in instead of a wobbly add-on pack.

The Timex Sinclair 1500 (1983) kept the ZX81’s core hardware and software compatibility but addressed its two biggest complaints in one move: a larger case with a proper keyboard instead of the touch-membrane, and 16 KB of RAM built straight into the machine rather than bolted on as a separate, easily jarred RAM pack. It arrived just as Timex’s US market position was collapsing under Commodore’s price pressure, and never sold anywhere near the numbers of the TS1000 before it.
