  I recently got the file midischem.lzh from ab20 and built the interface.

  Other than not knowing whether the actual chips are bad (I doubt it) I have
  checked and re-checked my work several times.

  The problem is that I cannot get it to work.

  I have a Casio CZ101 and tried MIDI in/out to MIDI in/out and
  MIDI in/out to MIDI out/in  and still nothing.

  The software that I have tried is:

  MED 2.3 , MED 3.0
  CZEd, AlgoRhythms, MidiTools --from the fish disks

  all did nothing.

  Then what I did was look up in my 2000 manual the pinouts for the serial
  port and noticed that pin 21 doesn't supply +5v as the schematic led me
  to believe (I have a new (2 mos.) 2000 if it matters)

  What I am wondering is has anyone gotten this interface to work, what
  programs does it work with, are there any updates to this schematic,
  am I missing something, or should I give up.

  Please let me know if anyone has any suggestions.


  Also- Since I did have fun building the interface
        (and now that I have all of the materials)
	are there any other hardware projects out there?
	Like a digitizer or something????OS


 ANY help would be greatly appreciated.

 Erik
