From what I'm told it sounds very like a
text-mode ASCII dumb terminal (Z80
CPU, ASCII display, diskless) - yet it has a network port on the back, rather
than an RS-232 connection to some other intelligent machine.
Chances are its just a serial port but with a network cable style
connector.
What is a 'network cable style connector'? If you mean a BNC socket, then
it can't be a normal RS232 port, since that needs at least 3 connections
(TxD, RxD, ground). Or is it an RJ45 (which could be RS232), or a DA15,
or what?
Is this the only external connector (other than mains)?
It's not uncommon for there to be a BNC socket on video terminals. Not a
network connection, but composite video out to an external monitor.
