The ZX81 was launched in 1981 by Sinclair and came in kit form for £49.95 or fully assembled for £69.95. The ZX81 offered 1KB of memory and an 8-bit CPU with a speed of 3.25 MHZ.

8-bit is an early computer hardware device or software program that is capable of transferring eight bits of data at the same time.
8-bit computer manufacturers Sinclair, Acorn and Tangerine (Oric) were all based within a few miles of each other in Cambridgeshire England.
Like many people the ZX81 was my first step into the computer world.
I bought my ZX81 by mail order in 1981 for £69.95 and still own the very same ZX81 today. I also recall purchasing the 16K RAM pack and the ZX Printer at a later date, probably still in 1981, but they have been lost over the years.
My fond memories of my ZX81 are based around spending hours typing in games from the magazines i subscribed to. I would play these games for hours and then lose them once i turned off my ZX81 - this is a far cry form the current XBox generation.
