Appendix

The GM829 problem can be cured by adding a second 270K resistor to the disk controller, in parallel across R13. This halves the hardware delay and appears to provide a remedy without introducing any other difficulties.

The problem with D.COM can be patched out using your favourite debugging tool to alter the code thus:

0944DD–>DD
094554–>E5
0946DD–>D1
09475D–>00

The addresses given are correct for the version of D.COM which I currently use (V1.6), other Versions may be different.
