The TC 3256 or Timex Computer 3256 was a computer created by Timex of Portugal, a branch of Timex Corporation.[1][2][3]
It was a third generation Sinclair ZX Spectrum compatible computer, with expanded capabilities and new BASIC commands supporting the AY-3-8192 sound chip, RS232 network and the 512x192 pixel high resolution graphic mode.[4][5]
Besides the legacy Sinclair BASIC, the ROM included a work processor (Timeword), Timex Extended Basic (with support for the Tenet[6] network, floppy disks and RAMdrive) and a CP/M Terminal emulator. RAM was expanded to 256k
The machine never reached the market since Timex of Portugal shut down its production line before its release.
