It was based on the Timex Sinclair 2048 prototype (see below), with a similar redesign case, composite video output, Kempston joystick interface, and additional video modes,[1] while being highly compatible with the Sinclair ZX Spectrum computer (although ROM differences prevented 100% compatibility).

It had an added Kempston-compatible joystick interface and a monochrome high resolution mode for 80 column text.

[7] In contrast with the ZX Spectrum, which was the best-selling computer in Britain at the time, the T/S 2068 and T/S 1500 were considered failures.

TC 2048 started to be sold in Poland in 1986, with 5000 units available at the "Central Scouting Store" for a price of PLZ 106,000.

This computer forms the basis of a proposal for an improved Spectrum-compatible machine, the ZX Spectrum SE.
