< I still have one prototyped at home... it allowed up to 9 voices
< (three voices/chip, 3 chips) of sound, and 3 voices of percussion.
I happen to have the DEC internal card for the Q-bus Ey-0105E-ms-101
(AKA Gigilo), uses two GI-AY-3-8912 sound chips. I also have some of the
PDP-11 software to drive it.
I don't have a schematic for it or the specs for the sound chips however I
do have a few sources for the music play software (asm a upower pascal).
I also have the honor of meeting Carlos in an old wherehouse and sound
lab on Long Island back in 1973 when the company I was with was moving
in to the facility. There was some amazing old junk left behind like
old audio power amps with 807s and 813s... It was just down the block
from SUNY farmingdale.
