Those articles were in Oct. '85 and Nov. '85 or Nov. '85 and
Dec. '85, although I believe the former is true.  A friend and
I built this hardware as a project for an electronics class
we were taking.  We used the assembly drivers from within
MegaMax C and had little trouble getting the Mac to send
information to the Ensoniq synthesizer we were using, but
never succeeded in teaching the Mac to listen to what the
Ensoniq had to say.  I blame this on my limited knowledge of
MacProgramming at the time and MegaMax's awkward use of
register A5 (SCC interrupts from the synth always crashed the
Mac...it's a long story).  For a class demonstation, we had
the Mac play the Minute Waltz in 2 minutes, then 1 minute,
then 15 seconds.
