File:Acorn 65C102 Internal Co-Processor Schematic (Simon Inns).pdf
Summary
[edit | edit source]A 5-sheet KiCad redraw of the circuit of Acorn's internal 65C102 co-processor board for the BBC Master (the Master Turbo board), by Simon Inns, 2019 (sheets: top level, logic, RAM, ROM, supply). It shows the Tube ULA, the 65SC102 with its 16 MHz crystal, and the decoupling capacitors A1 to A21 (100 nF). It is a modern reconstruction, not an Acorn drawing.
