ISTR the ADM5 was their first microprocessor-based product. The ADM-3a did=
have MSI serial components - as I recall, it was two separate chips for tr=
ansmitter and receiver, but still single components for each rather than SS=
I am suprised it didn't use one of those 40 pin dumb UARTs, like the 1602
/ AY-3-1015 etc. The only separate Tx/Rx chips I've come across were the
ones HP used in the 11284 (serial interface for the 9830) and 59403
(common carrier interface for HPIB) and supproted synchronous operation too.
