Far as I know, the Disto drivers will work with PCDOS. At least it works
on my system.
I have a hunch Charlie is trying to read a high density disk instead of
a medium density disk on the Coco. That is not going to work.
If it turns out Charlie was using an appropriate disk, I do have a
driver that will with a Disto SCII. I just need to know which addresses
are being used, $FF58 or $FF74.
