Picture of the parallel port drive i am using is attached. Looks like it 
will be pretty nice if i get it working, i picked it up in box at a 
scrapyard, the driver floppy was destroyed beyond reading, and took me a 
while to find the drivers for.


I appreciate the advice on the drives. I do have some spare 720K and 
1.2MB drives, if one of those will work with the stock controller it 
will be of much better use to me. I do have interest in being able to 
use it on an external monitor  so ill look into tracking down a Zenith 
version of dos.

DOS software is the main focus, not really interested in windows. I have 
an 8 bit ISA sound blaster card, i want to see if i can get some music 
tracker software going on it, or perhaps a BBS / JNOS .
