I pulled out the boards (and made scans of them while I was at it --
http://yahozna.dyndns.org/computers/cdcterminal/pcb -- warning, really
large images again so as to make the chips readable.) I think, if I'm
deciphering the date codes correctly, that the components are from
I also got a response from the folks at cray-cyber.org. They don't know
much about it either, but they think that it's probably a CDC 711
terminal (possibly a 713, though the 713 only supported 300 baud), and
they even dug up a termcap entry for it (which I have yet to try):
C3|713|cdc713|Control Data 713:\
and a bit more info:
Control Data Corporation 713
Status: Supported by ":CRTSTY CDC713".
Price: forgotten in the dawn of time
Screen: 16 x 80
Chars: 7 x 9 with descenders
Has: Random, CLEOL, CLEOS, Standout
Lacks: Addr, Tabs, InsChar, DelChar, InsLine, DelLine, Overstrike
Misfeatures: 300 baud maximum speed!
Additionally, the description at http://www.museumwaalsdorp.nl/computer/en/cybequip.html seems to match what I've got pretty closely.
So that's it. Seems like this'd be a nice terminal to use with my
SBC6120 (may just mount it inside given how much room there is :))
Thanks for all the feedback and input. Nice to know a bit more about
