	Good question, with comp.sources/net.sources in limbo where would
   it go? By posting it here we could "keep it in the family" so-to-speak.
   I'll need some definite I want its before I burdon USENET with my code.

	If you have a cassette based four the model 3 disk interface might
   work in it as well as the RS232. Email me if you think you might like
   to look into this. Your best bet might be to upgrade the disk based 3
   to a four or buy a disk/memory upgrade kit for the 4.

	My terminal program allows disk only I/O. I spent 6 months totally
   rewriting the terminal program for a lousy PD one I found. My terminal
   program has to run under LDOS 5.x in order to work properly. I have 
   termcap and terminfo files for it. If anyone is REALLY interested I'll
   write a whole article on it.

>Do I have anything anybody else wants?  Does anybody else have anything
>I can use?

	What kind of programs are you looking for? My only other original
   work is a disk zapper that uses it's own I/O routines; It doesn't do
   any error checking so you can wipe out disks as fast as you can fix 'em.
   I have a double sided version for zapping IBM PC disks on a 3/4. Anybody
   interested?
