Make sure you keep and eye out for data errors on the SCSI and floppy
without a clock patch installed. It will seem to work, then all of the
sudden, you have a bunch of missing sectors (or simular).
I use the normal "Atari" clock patch on all three of my
machines, and not the one that comes with Nemesis. The sharp
bend of the trace near the SDMA seems to be a problem area, and
even on stock machines I run a good quality wire from the resistor area
near the cpu to the DMA trace/cut area. If you ohm the line, the
fpu clock is tied into that trace as well (and I don't think it was ment
to be that way) and leaving the DMA trace cut kind of elimates any trouble
that may cause.
Good to hear that it is working!
