I wish I had these schematics. But thanks for thinking of me. ;)<br>

<pre wrap="">The Buchla 500 is basically a 200 with a computer interface. There was no
special circuitry in the modules themselves - they were vanilla 200. The 500
had a few I/0 port modules, which were unto themselves and probably had
drivers, maybe DACs and ADC's??? Only three 500s were ever made to my
knowledge...good luck finding prints!
Pardon me if this reads like the beginning of the Lord of the Rings:
1) One was at Cal Arts, sold off in the mid 80's. In the pictures linked
below, can see the I/O modules right above Mort's head and the CRT next to
his left ear. The thing barely visable under the CRT is the corner of the
QWERTY keyboard. Jill Fraser is the blond in the photo with her legs
crossed -there's more on her in a second:

2) Another is still installed at Evergreen College in Washington State -
note interface next to output module:

3) And I third ring made it to the elves. Ah...i think a 3rd 500 made it to
Europe? Rick?
If I *really* had to track down schematics, I'd try the tech person at
Evergreen, whoever that is. Don, forget it. John Payne would be the only
faculty guy at Cal Arts who would possibly know, but he retired a couple of
years ago and I'm pretty sure when the 500 left he looked skyward, said
thank you and threw the books in an incinerator.
If you can track down a guy named Ray Wersching (not sure how you spell
that), he was the guy at Cal Arts who had the hood up on the 500's computer
most of the time, but most of that was s/w. You must remember, it was
archaic even before it was old. There was no storage outside of ram and a
punch paper tape reader on the teletype. You had to MANUALLY load the
operation system on boot up with a series of 16 switches on the faceplate of
the machine and that operating system was never completed. Jill Fraser
worked with it like a dog for six months generating the control tracks for
Subotnick's Game Room and Sky of Cloudless Sulfur from his scores. The
thing was a mess.
hope this helps.,
