I built a BBC MIDI interface back in '89 - it still works wonderfully.
It's address configurable, so if I ever I found out what address the AMPLE
system expected to find a MIDI port at I could set it to it. The circuit
diagram is on PD disk JGH-007, I could post it to the group if the
moderator agrees (3.5k).
 
With it I wrote some intercept code that redirected SOUND commands to the
MIDI port, so almost any generic music-playing program played through the
MIDI - as demonstrated most years at the NTAUS.

Could anybody tell me or point me to information about the specification
of .ssd and .dsd so I can add them to HADFSFiler image filing system.
 
Thanks!
