It's probably one of the old MDA/CGA/EGA monitors, and would be no use
for you if what you want to do is to hook it to your Mac as a serial
terminal.

Get a serial terminal (made by DEC, Wyse, and so on) which is basically
a small computer with fixed functionality.

If I were you, I'd get a cheap used PowerBook or notebook PC instead.
That way I could use it to do other things than as a terminal.

To connect two Macs, you can use a printer cable (Apple System/
Peripheral-8 Cable M0197LL/B or equivalent).  To hook up a PC to a
Mac, get a Mac-to-modem (DIN8(male)-DB25(male)) cable and a PC-
to-modem cable (DB25(female)-DB25(male) or DB9(female)-DB25(male)),
and connect the two cables with a null modem adaptor.
