I built a MIDI interface that was originally designed for the Amiga 1000
several years ago.  A friend of mine adapted the power input for the
500/2000/3000.  It works just fine.  On mine I have two MIDI/in, two MIDI/out,
and one MIDI/thru port.  I will check out the one posted on ab20 and if it is
not the same thing, I will see about posting my own project schematics.  (IF I
can find the disk ;-)

Oh, and it works with everything I have tried it with... MED 2.0/3.0, Tiger Cub
(gasp!), and Bars & Pipes.  It has been used with a CZ-101 and a Roland MT-32.

I have schematics for two audio digitizers.  They are both basically the same. 
Mono, max speed only 14000 samples/sec, and the sound is not exactly commercial
quality.

I also have schematics for a Digi-View clone.  That one looks like a real
handfull so I haven't (and probably won't since I wouldn't have any software
without buying the real DigiView hardware) built it.  Those schematics MAY be
on ab20 as well.  I'll check if you are interested.
