=== Timex Sinclair 2068 ===
The TS 2068 was released in november November 1983. It was Timex Sinclair's third and last home computer for the United States market.
It is a more sophisticated computer compared to its UK ancestor, the ZX Spectrum. It added a number of new features:
Because Timex added more commands, the ROM could not fit on 16K so an 8K ROM was added. Timex moved some of the original ZX BASIC commands to this new 8K ROM, making programs that used ROM routines unusable.
With this change, only about 7% of ZX Spectrum software worked on TS2068. Using a ZX Spectrum ROM cartridge fixes it, raising compatibility to 97%.
