Hi
 Sorry about that, it isn't on a Coco. I'm doing it with
a 80C186EB processor and a iSBX board that had a 2793 floppy
controller chip. It was a surplus board I picked up at a
local surplus place called HSC.

 I looked at adding subdirectories to my code but, at the time,
I couldn't justify it. It really didn't seem all that hard although it
did look like a hack job by the fellow that wrote DOS. The code was
written with the only purpose of transfering ASCII text from
my BLOCK files to a DOS disk. It had no frills. I don't
recall all the ins and outs of it but it looked straight forward
enough. I think I wrote the DOS code in '91 so I'm not to up to
date on exactly how it worked.
