What is a ZX81:

The ZX81 was the successor of the ZX80 and one of cheapest home computers. The things that made the ZX81 so cheap was the membrane keyboard and there were only four chips in the ZX81 (in some ZX81 5 chips): the CPU, ULA (logic chip), 8 KByte rom and 1 KB ram (there was no graphic chip; the CPU had to do the job).
The ZX81 was also available as Do It Yourself kit.
There was a memory expansion pack of 16 Kbyte wich was connected to the expansion bus.
You could use a cassetterecorder for saving programms and there was a special ZX81 printer.
