Acorn 65C102 Co-Processor User Guide

The 65C102 co-processor user guide is Acorn Computers' fitting and user guide for the internal 65C102 co-processor board (sales code ADC06) that turns a BBC Master 128 into a Master Turbo. It is part number 0443,030, issue 2, dated April 1986; the copyright page says it was first published in 1985. The hosted scan has 16 PDF pages and an OCR text layer.

What it does not contain

The guide covers fitting and use only. There is no circuit diagram, parts list, power consumption figure or fault finding beyond checking the configuration with *STATUS and re-checking the fitting (p. 7). Fault finding for the internal co-processor is in section 7.13 of the BBC Master Series Service Manual, which also has no circuit or parts list for the co-processor board itself.
