it sounds like they are plated brass, then.
I had been considering trying molex pins, but apparently that's going
to be a poor choice.
Good to know. Chicago Lamp or someone ought to have something that works.

They are not ordinary, at least I haven't been able to find any like them.
They are brass taper pins, about .093" at the tip and about 0.1"
higher up. The brass part is important. I tried using the regular .093"
pins and splaying the backside slightly, but it did not work as well, and
the steel or whatever the new pins are made of scratches up the little brass
rings. I looked through the manuals, and there's no
information about jumper
lengths or quantities in there, at least beyond what was already reported.
OK.

According to the student manual, they are DEC #12-5591. According to the
DEC parts list, that's a CM2306. The CM2306 is a 6V 20ma bulb
with a brightness of 0.600mscp. (I'd guess that let them be run off the same
supply as the logic.)
Probably.
Thanks for the info, Vince,
