MIDI for Roland CMU-800R?

I'm wondering if anyone has done any work towards MIDIing a Roland
CMU-800R. I just picked one up cheap because I >thought< there was a MIDI
retrofit floating around; I was wrong.

If you don't know what the CMU-800 is - it was Roland's first "computer
music" product. It contains a TR-606 type drum sound generator, 6 voices of
cheesy analog sounds, and - most interesting - 8 CV/gate outs. It was
designed to work with the Apple II and the Commodore 64; they provided
cheesy sequencing software for it. It was discontinued shortly after it was
released, when MIDI came along, so it never made much of a splash.

Programming info is available for it; it would make a great platform for
DIY MIDI/CV projects. I'm not inclined to do this myself because I want to
put my DIY efforts towards modular synthesis; but if someone has done the
engineering work, I could be persuaded. Or I could sell it cheap if someone
else wants it.
