BTW, does
anyone know if there were 3rd party 80-columns upgrades? A while
back, I got a disk from Don Maslin which was supposed to be a 80-col
boot disk. Although it booted fine on his and several other systems, it
would never boot mine. I later tried reinstalling the patches on the disk
to a fresh copy of CP/M- no luck either. It also crashes totally when I
try to set the baud rate of the "programmable" clock generator referenced in
the README for the disk.
That would be the one that is listed as the OS1NUEVO in my SYSDISK list.
I don't know the answer to your question, John, but it is certainly
possible. Do you now have a bootable SSDD-80 column disk for your
machine? I'd be interested in a copy to compare.
Nope. Interestingly, if I use SYSGEN to load the CP/M from the disk after
it is booted, it will switch into 80-col mode and stay that way until
powered off.
Possibility 2- I wonder if some jumpers are set wrong/different.
