Still trying to make some progress on the PowerUP SCSI
controller. I noticed that when I try to read back the value from the dsp
register that it is not the same as the value
that was put into it which is the "pc" value Does anyone
think that is strange? Assuming the SCSI chip did not change the value
for some reason, one would think it should be the same as what was put
in.
