Paul, are you thinking of the General Instruments AY5-1013, or did that come later? That
chip was in an 8008-based option board for the Tektronix 4014 graphics terminal.
(Internally called the figpi, first gen peripheral interface. The sigpi was a 6800.) I had
a look at the firmware when I started at Tek in 1980.

General Automation UART chip, I think that was the first single chip UART, which made
the job a whole lot simpler.
