The Sinclair ZX80 microcomputer was an innovative product introduced in 1980 by Sinclair Computer Ltd in Cambridge, England. It was among the first affordable home computers available in the UK, designed as an accessible way for the public to engage with computing.

Key Features of the Sinclair ZX80:

  1. Design: The ZX80 was encased in a white plastic shell containing a single printed circuit board. Its front housed a small black keyboard, a membrane type with printed keys in grey and red. The minimalist design kept production costs low.
  2. Ports: On the left side, there were four ports designed for connecting peripherals:
    • Two for a cassette recorder (for data storage and retrieval),
    • One for a power supply,
    • One for a TV cable to use a television as a display.
  3. Expandability: On the right side, a slot allowed connection of a RAM pack to expand its memory, addressing its otherwise limited built-in memory capacity.
  4. Specifications: Powered by a Zilog Z80 processor (hence the name ZX80), it operated with 1 KB of RAM, expandable to 16 KB. It ran on BASIC programming language, which users could input via its keyboard.
  5. Display and Usage: The ZX80 is connected to a television to display text and basic graphics. It was primarily used for programming in BASIC and for running simple software.
