SCSI questions
No other boards, but problem solved! I think. 🙂 A few more minutes with
GVP revealed that this particular hard disk controller was a very old model,
known not to work with Rev 4 motherboards. (Oh yeah, I forgot, there are no
differences between motherboards. Seriously, the problem was GVP's, they had
about 1 volt of ringing between an address and a strobe line…) So I have a
new controller coming tomorrow morning.
Second half of the trouble was that the 2090A (new CBM) controller *requires*
the 1.3 ROM to even work at all, so when I borrowed the friend's controller, it
wouldn't work because I had 1.2 ROMs. Isn't this fun? I have a 1.3 ROM coming
tomorrow, too, so I should be online RSN.
