Does anyone out there have schematics for a debugging board for the IBM PC? I know that the Atron card and the IBM Proffesional Debugging Board can assert the NMI line to invoke Symdeb. I would like to duplicate this facility for myself. I have tied a debounced pushbutton to the -iocheck line on the backplane, but it has no effect. Are there any timing restrictions to this? Any additional information would be greatly appreciated. -- ------- Computing is a human activity. David L.
