Re: Software for MS-DOS 1.25

There is a lot of CP/M 86 software for this card, I have quite a few disks
including I think WordStar.  The MS DOS port is pretty much an experiment
IMHO.  Aside from the fact that most IBM PC software requires DOS 2 as it
is, it's probably going to be slim pickings.  I do have a collection of DOS
1-compatible software for the IBM PC, might as well try all of it and see
what works.  I have an article about how the port was performed, there is a
process for running DOS on a non-IBM PC.
