I think I picked up one or two of these power cables
last year, they are
definitely old and used. I'll see if I can find them on Monday.
They are used on Teleray terminals, a Modem tester (with Nixie Tube display)
that I have, etc.
Ah, Teleray... I remember these well from my Prime days (they were the
only CRT-based terminals we had, everything else was a DECwriter).
A sales representative came to our site (we were the Computing Services
for the local public school corp), and we explained that since students
would be among the users of these terminals, they'd have to be pretty
sturdy.
Well, we're up on the second floor of this building. The sale droid
pulls out a screwdriver, removes the Teleray metal cover (almost all
metal boxes IIRC), pulls the CRT and yoke harness, sets them aside,
puts the cover back on, and *kicks* it down two flights of stairs.
He brought it back up,removed the cover again, replaced the CRT &
yoke assembly, put the cover back on, hooked it up, and it worked!
"Sold" said my boss...
