Unexpected DIY project

[patchell]

    Well, what I have in mind for the thing is probably really going to
pervert it.

    It is already pretty perverted.  I used to sell a memory/io expander.
It also has another board I did that has a 2716 eprom on it.  When I made
that board, the 2716 was a pretty big deal.

    The main problem right now, is trying to get the software off of my old
Atari800.  I wrote all the software for it using the Atari Assembler Editor
cartridge.  I don't know if I am going to be able to put the system back
together enough to get what I need.

    The 8700 keyboard was originally purchased to interface to this synth:

    I hope that link works.  Anyway, I had a custom interface to the synth,
wrote all my own software.  It even had a crude sequencer that would run in
the background.  Anyway, I am trying to get all that old stuff running
again.

    Actually, if you want any of the old memory/io expander boards, I still
have a few blank ones.  It uses a pair of 2114's and a pair of 6522 VIA's,
and some misc TTL stuff.  I would have to look in my junk box to see if I
have any of the old PROM boards, or, for that matter, the 2716 burner card
(I used to use the 8700 as a prom programmer as well).
