Seems to be RS-232 compatible, which in my experience is unusual for a terminal in the
early half of the 1970s. It has little serial number stickers tucked around but
they're all random numbers, nothing really lines up. A few of the boards have what
appears to be serial numbers in the low hundreds.
So tempting to just plug in and see what happens, but I'm concerned about the voltages
on two pins that seem off.

Brad,
That's a new one on me.
But the split CRT reminds me of a 1970s IBM desk computer (it was a computer built into a
desk, I forget the model number) and it had a similar display.
I wonder if this isn't some third-party IBM compatible terminal?

Hi there - not sure how much overlap there is with
vcfed's forum, but
thought I would reach out here in case. I have a terminal from 1974
(based on date codes I've found on the motherboard). I'm unable to
determine manufacturer and that would be handy for diagnostic
purposes. The terminal casing is made out of foam, and although there
are some serial numbers stamped around, nothing really lines up. The
fans inside have zero dust or dirt, so I'm thinking this may not have
seen much use, or may be a prototype or pilot for something. It does
have RS232 capability. Interestingly the screen is set down below the
keyboard so that only half of it is visible.
My main issue right now is the PSU - I am trying to determine if I'm
safe to attempt powering up the board (the PSU so far seems to be ok,
although some voltages on a couple of pins are mysterious).
Anyway, on the extremely off chance anyone has ever seen one of these
or something like it.. any tips would be appreciated. If I can find a
manual I'll feel a lot safer about turning it on.
