Right before I go to eBay with this - I know there are a couple or three
Musicians here - I have a 1977 Yamaha CS-80 8-voice polyphonic synth for
sale. I thought to take a chance on Classiccmp - one never knows...
If you know what this is, and you're interested, please contact me
off-list for more details. I have the Service Manual for it, which is now
made purely of Unobtanium.
Hey - it *does* have a special-pupose computer chip in it: the Keyboard
Scanner / Note Multiplexer is a very early CMOS mask-programmed "PLA" sort
of thingy... so I'm not too far off-base here.
Cheers
John
