DOS 3.20

I believe DOS 3.20 is what I was looking for. It came as original software
for a Packard Bell 386/12T (don't remember the specific model name), and I
used the accompanying book to teach myself DOS programming -- back in
1991... The system had dual floppies (both sizes), a small hard drive, no
sound except for the system speaker, and one of the first mass production
.25 dpi monitors. I paid through the nose for the system at the time, but
I'd likely give an arm and a leg for that old DOS manual...
