Has anybody else had a problem with turning on their 1571, shoving a disk into
it, turn on the C128, watch BASIC 7.0 copyright message come up, and then --
lockup?
I have very early model C-128 and 1571 (1571 has ROM upgrade, C128 doesn't).
Is this some problem in the disk routines that was fixed in the new version
C128 ROMs?
Also, nobody ever did answer my question about 6551 interrupts. I have my 6551
hooked to the NMI's right now, so that I don't drop characters. But from
looking at the C128 schematics, it looks like they should go to IRQs, because
that's all that goes to the Z-80. Since I know little 8080 assembler, and even
less about the structure of Commodore's mangled CP/M version, my glances at
the device driver sources have been less than enlightening...
