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:
| 0944 | DD | –> | DD |
| 0945 | 54 | –> | E5 |
| 0946 | DD | –> | D1 |
| 0947 | 5D | –> | 00 |
The addresses given are correct for the version of D.COM which I currently use (V1.6), other Versions may be different. ●
