BBC Microcomputer System

Forgotten Technology · 1981

Published

Acorn designed and manufactured the BBC Microcomputer System to meet the BBC's specification for its Computer Literacy Project. Introduced in 1981, the 6502-based machine combined built-in programming tools, expansion interfaces and educational support.

Why It Mattered

The BBC Micro joined broadcasting, schools and home computing within one coordinated project. For many British users it provided an early shared introduction to programming, computer hardware and digital literacy.

System & Models

- 8-bit system based on the 6502 processor family. - Model A had 16K RAM; Model B had 32K RAM. - The original BBC Microcomputer System comprised Model A and Model B variants.

Built-In Facilities

- Facilities included BBC BASIC, colour graphics modes, sound and cassette storage. - Video, serial, analogue and Econet interfaces were among its connectivity and expansion options.

Computer Literacy Project

- The BBC issued the specification in January 1981, and Acorn won the contract in March 1981. - The wider Computer Literacy Project formally launched in January 1982 after supply delays affected the computer rollout. - The project combined broadcasts with books, software, helplines, local courses and tutors.
