General Instrument. Often there's a "GI" logo on their chips. Dennis Boone wrote:

(Yes, the AY-5-1013 is a hardware/switch/pin-configured UART. Can supply
pinout if needed.)
That may be why I was recalling that number. The other one of those being
what, a 6402 or similar? I'm thinking Standard Microsystems, for which I
do have a databook someplace though I haven't seen it in ages.

AY-5-1013 40 pin dip (cpu?)
UART, I think. I know I've run into that number somewhere before.
