Hi,
I knew I still have that General Instrument 1977 Product Guide leaflet
in my dusty library of ancient electronic stuff. I just dug it out, and
after some polite negotiations with those spiders, they finally let me
read it.


AY-5-8320 is a chip for digital channel/time display on a TV screen. 17V
supply. Quite exciting back then, but now...

As already stated by others, AY-5-1013 is a UART, usable up to a
whopping 40 kbaud. Whew... And it only needs +5V and -12V. Say good-bye
to those 3 supply chips... ;-)   
Said to be a pin-for-pin replacement for the Western Digital TR1602A.
I _might_ have a data sheet hidden somewhere, but I guess it's not worth
it anymore. There are other UARTs around today for cheap.

Sorry, no further details, pinouts etc. available in that leaflet.

So, both are of no great use for synth diy. Although GI had some top
octave divider chips as well...

bye
Christian
