- Q2736931 abstract "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. It was Acorn's first product, and was based on an automated cow feeder.It was a small machine built on two Eurocard-standard circuit boards and it could be purchased ready-built or in kit form.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 CUTS interface (the circuitry to the left of the keypad)the second card (the computer board - see below), which included the CPU, RAM/ROM memory, and support chipsthe two boards were interconnected by a semi-flexible, multi-conductor cable, known by its commercial name 'Spectra Strip'the whole assembly was held together by four 2.5mm × 20mm nylon screws and clear plastic spacing tubes for rigidity. Main Components (left to right) Top Row: INS8154 RAMIO Integrated Circuit (for keyboard and display), 6502 CPU, 2 × 2114 1024×4 RAM, 2 × 74S571 512×4 PROM, RAM/ROM expansion socket, second INS8154 for peripheral expansion (optional extra with the kit version). Bottom row: 1 MHz clock crystal, 4 × TTL logic chips providing address decoding for the memory and I/O expansion, 5V regulator. The smaller empty socket in the middle of the board was used to set the memory map of the RAM, ROM and I/O expansion by fitting or soldering wires between various positions according to the instructions in the Acorn System 1 Technical Manual.Almost all CPU signals were accessible via the standard Eurocard connector on the right-hand side of the board. This connector was not fitted/supplied as standard with the kit version.".
