The Sinclair ZX80 was one of the first real home computers - it was supplied in kit form only to home electronics enthusiasts and was fairly easy to build up into a fully working computer, complete with built in BASIC interpreter, Z80 processor and a massive 1K RAM (random access memory).  It was the first in a line of computers from Sinclair Research (developed by the British inventor, Sir Clive Sinclair), to be released onto the market and they all eventually built up a devoted following, despite the infamous Sinclair delivery date of "28 days" (which could be anything up to 6 months).

The Sinclair ZX80 was an all-white computer, although both a white and a black PSU were released for it (both bear the markings Sinclair ZX80).  A 1K, 3K and 16K RAM pack were soon to follow, again released initially in white.  The 16K RAM pack was later released in black.  However, the white PSU and RAM pack are especially rare, mainly due to a large number of returns of the white RAM pack.

The standard Sinclair ZX Printer released primarily for the ZX81 computer, also worked with this model, although the power supply was insufficient and a newer 1.2A power supply unit was released for use with the printer - unfortunately, neither the printer, nor this bigger power supply were ever released in white.
