tricked out with options, or mine is indeed missing some cards.
IIRC, the cardcage drawer in the 4002A was pretty well populated.
There weren't all that many options that I am aware of -- mostly
communications related, and didn't take that many slots. There was a
parallel interface for faster transfers, some kind of option that
allowed a high-speed non-serial connection to a PDP-11-class computer
(Unibus), and the usual RS-232C and current-loop serial interfaces. As
far as I know, that was about it.
I'll keep my fingers crossed for you that your terminal isn't missing
any cards! Good luck with restoration and bringing it back to life.
These are truly classic, and rare terminals. I have many fond memories
of using these both at OMSI (Oregon Museum of Science and Industry) on
their
Digital Equipment "Straight-8" (1975 or so), and also for quite a few
years at Tektronix in the late '70's. The 4002's were quite common then,
but quickly replaced with 4010's as the terminal of choice for
connecting up to computers in Tektronix' data center (CDC Cyber
73-KRONOS, VAX 11/780-VMS).
