Acorn System 5

The Acorn System 5 was the final Acorn rack-mounted system, released in 1983. It was mounted in an extra-height single 19-inch frame, which could accommodate two vertically mounted 5 1/4-inch floppy drives, with either seven or ten Eurocard slots. It came complete with a power supply, and was only available fully assembled. As standard it had a 1 MHz 6502, 32K DRAM, a disk controller, and either the 80×25 or the Teletext 40×25 VDU cards. Customers could choose which cards to install in the remaining slots, including interface cards, an additional 16K DRAM card, and/or an Econet network adapter; they could also choose to upgrade the processor board to a faster 2 MHz 6502 board.
