ever looked inside one of these things?
Late one nite, I had nothing better to do than poke around
stuff in the computer lab; indide I found one *big* board,
covered with what I think was TTL. No uP, all random logic,
*no* processing overhead.
Yes and I bought mine(ADM 3A) (new) as a kit. I got that big boards and
a box
of chips that had to be hand soldered on to the board. The CRT and it's
board
were pre assembled. It finaly gave me trouble and I junked it.

At the time, they were fairly cheap in comparison

Computer Network back in the early 80's and we used then for that
reason. Most
ran at either 9600 or 19200, but we modified a few to run at 38400
and they
could keep up with that speed as well...
