Timex Computer 3256
The TC 3256 or Timex Computer 3256 was a 1987 computer created by Timex of Portugal, a branch of Timex Corporation.
It was a third generation Sinclair ZX Spectrum compatible computer, with expanded capabilities and new TEC - Timex Extended Commands BASIC commands supporting the AY-3-8912 sound chip, RS-232 network and the 512x192 pixel high resolution graphic mode.
Besides the legacy Sinclair BASIC, the ROM included a word processor, Timex Extended Basic and a CP/M terminal emulator.
RAM was expanded to 256kb.
At least one prototype was built, but the machine never reached the market due to Timex of Portugal shutting down its production line before its release.
