9 bit memory also was rare.
Not quite lost. The 1802 crowd is doing amazing things.
See https://groups.io/g/cosmacelf/message/33678
And if you know anything about the 1802, it's, uh, not so speedy.
At its introduction,it was one of few static CMOS CPUs. You could run
it from batteries and stop the clock when not needed. Perfect for
telemetry. I think the Intersil 6100 was another, but required 12-bit
wide memory.
--Chuck Did any use a INDUSTRY STANDARD UART, with a external
FIFO chip?
The DEC DZ11 uses the standard 40 pin 'dumb UARTS' and feeds the
receive data into FIFO ICs. I am sure there are others.
