#### Sinclair ZX 81 / Timex Sinclair 1000

History and Trivia:
The Sinclair ZX 81 was the successor of the ZX 80. It had the same characteristics as the
ZX 80, it's main difference (except for the colour) was its higher level of integration: the
ZX 80 used about 12 chips which had been replaced with a ULA in the ZX 81. This computer was
very successful in Europe at the beginning of the 80's. A large range of peripherals were
developed for the ZX-81, among them: 3.5" floppy disk units, high resolution graphic cards,
RS232 or Centronics interfaces, and RAM extensions. The ZX 81 was sold as the Timex-Sinclair
1000 in the USA.
