Description
A Sinclair ZX81 ( from 1981 ! ).

This computer has a massive 1K of RAM (1024 bytes!) (expandable) and 8K ROM. It uses a Z80 microprocessor, and a membrane keypad. It uses a dometic TV for the video output, and loaded/saved programs using cassette tape. This was my first computer, and is now 24 years old - but still works!
