Acorn System 1

The Acorn System 1, initially called the Acorn Microcomputer (Micro-Computer), was an early 8-bit microcomputer for hobbyists, based on the MOS 6502 CPU, and produced by British company Acorn Computers from 1979.

The system was designed by then-Cambridge-undergraduate student Sophie Wilson.^[1] It was Acorn's first product, and was based on an automated cow feeder.^[1]

It was a small machine built on two Eurocard-standard circuit boards:

one card (shown right) with the I/O part of the computer: a LED seven segment display, a 25-key keypad (hex+function keys), and a cassette interface (the circuitry to the left of the keypad)
the second card (the computer board), which included the CPU, RAM/ROM memory, and support chips.

Almost all CPU signals were accessible via the standard Eurocard connector.
