I can't recall your original posting, but are you saying that you're
having problems with Nemesis alone? If that's the case, is this at all
speeds (16, 20 and 24MHz) or just 20/24?
If you've already installed the AB as well as the Nemesis, then just stay
away from the accelerated modes. In 16/32MHz it should be stable, but
getting stable SCSI in 20/40MHz is quite a job.
If it's not stable in 16/32MHz, then you'd have to tweak your
installation. Firstly, install Doug's inductor/resistor-mod (Doug, is your
homepage still up?) and try tweaking this with different resistors. This
should do the trick, if not then you have to start fine-tuning the rest of
the machine:
o Replace the white wire from the clock-patch to the DMA with a piece of
shielded wire, and ground the shield in both ends.
o Shorten all Nemesis/clockpatch-wires as much as possible.
o Ground the Nemesis really, really well.
o Shield the entire underside of the AB with multiple layers of foil. Be
careful not to short-circuit anything!
o Shorten and shield the wires from the GALs to the AB.
o Replace the 500KHz-clock to the MIDI- and keyboard-ACIAs with a new,
stable one (sorry Doug, but the Nemesis is really bad at this point...)
Not all of these tips are directly related to SCSI-stability, but anything
that improves stability in general will do. I've done all the above, and
while the Falcon itself is 100% stable in 40MHz now, SCSI and floppy still
doesn't work >32MHz...
