I like the idea of the above, but why do I remember that the MIDI
port was hardwired to a timer that gives you 31.5 Kbit/sec (or whatever
MIDI is, I forget exactly).

And it as also been my experience that MIDI cannot even rrun reliably
contiuously at 31.5 Kbps becuase the ISP runs at low level (I think 1),
below every thing else.  So I doubt that it would be anywhere near
reliable enough at 500 kps!
