Hi John,

I don't recall too much about this thing except that we sold a bunch 
of boxes to Bull that had a 3.5" and a 5.25" floppy in them connected 
to a compaticard.  

You can easily make this run without the external setup by just 
editing the DISKETTE.CFG file.  The code has drive X:  defined as the 
3.5" drive and Y:  as the 5.25".  

There's something itching at the back of my mind that says that the 
DPS9000 3.5" floppies were of the 360 RPM persuasion and not the 
usual 300 RPM.  If you're interested in handling the 3.5" media and 
don't have the appropriate drive, I can tell you how to modify a Teac 
FD-235HF to have it run at 360 RPM.  

The LHARC archive contains a self-extracting diskette image file 
(720K 3.5" DS2D media).  Your ISP doesn't like EXEs sent in ZIP files 
is blissfully ignorant of LHARC--WinRAR should unpack the archive 

I can probably provide source code, but I'm going to have to puzzle 
the thing out--it's been a very long time since I've looked at it.
