I'm assembling a PDP-8/a from a pile of parts, but I'm missing the entire
AC power entry assembly, as shown in
http://www.retrotechnology.com/restore/8a_trans_gnd0.jpg. Does anyone know
what the 6-pin connector is? Even better, does anyone have an extra
assembly?
Thanks to Herb Johnson for the 8/a repair write ups (
http://www.retrotechnology.com/restore/8a_repairs.html) and pictures. Very
helpful!

That connector is still being made! It's an AMP Mate-n-lock:

Well, okay, it's not "Amp" anymore, Amp's been eaten.

Awesome, thanks! I missed that in my scan of the Mouser catalog.

$0.86 for the connector, $160 for the crimper.

I have the crimper (for the cable on my FDDC boards). If you send me
terminals and wires, I'll crimp them and send them back. Although,
you can usually get away with needlenose pliers and a little solder
if looks aren't important.

You should be able to use Molex crimping tools with these
contacts with a little care.
The contacts are quite similar. You can even use needle
nose pliers, but you will end up mashing more than you crimp
properly. Then, you will need to solder them to get a good
connection.

I'm pretty sure this is an AMP Mate-n-Lock connector. I
think they are still made.
DEC used a lot of them in various power supply/distribution
areas.
