I'm on eof the few who actually put up $50 for the MIDI port, and ISTR you 
got the descriptor and driver for it then, and not before.  You are right, the 
MIDI "paddle" board-let is different from the RS232 serial interface.  The MM/1 
mother board talks in standard 5V TTL to the paddle board, which converts in 
and out of MIDI current loop.

ISTR I bought it from David Graham, not Paul Ward.  Whoever it was, frankly 
admitted to me that the $50 for this little board with 6 parts on it was to 
help finance other MM/1 developments.

For me personally, no price was too high for MIDI on the MM/1, but it irked 
me that its connector was not the MIDI DIN smiley-face, but the same old DB-9 
as used on the RS232.  You had to make your own adapter cable.  And I never did 
get around to wiring an *input* side of it.  A shame, since the MM/1 could 
probably have read MIDI and time-stamped it in real time, unlike the Coco under 
OS9.
