The TC 2048 or Timex Computer 2048 is a computer created by "Timex of Portugal, Lda", a branch of Timex Corporation.

It was highly compatible with the Sinclair ZX Spectrum computer, although differences in the ROM prevented 100% compatibility. Timex Portugal only sold the TC 2048 in Portugal and Poland, where it was very successful. Also, this computer forms the basis of Andrew Owen's improved Spectrum-compatible machine, the Spectrum SE..
