The Acorn System 4, released in 1982, is a disc-based computer housed in a double-height rack with the capacity for up to 14 Eurocards. The basic system has two floppy disk drives, power supplies, card frame buffered backplane, 6502 CPU, VDU interface, 16K RAM and disk controller as standard.

This System 4 case contains some of the eurocards, but is missing the two disk drives that fit in the top rack. There is only an 8K static RAM card, and no Operating System in ROM.
