[GreenKeys] BRPE punch

[Nick England]

The mating female AC power connector is Hubbell HBL7484 Midget Twist Lock,
which is a NEMA ML-3R.
You can find them on eBay, etc. Whenever I see one at a hamfest I grab it
for future use.

Quote from Don House in 2010 -
>>NEVER USE UN-OILED PAPER TAPE IN TELETYPE MACHINES.
