[GreenKeys] More cleaning up!

How many plugs are needed for the computer?  I can scour the closing surplus store for some minibananas that might to the job.  Maybe they'd have some dual plug pieces.
There were HC-6 like crystal sockets that had FT-243 pin dia & spacing.  Lots of those are probably of no interest to anyone & could be disassembled to make plugs.

Hi Jeff and List -  (OT)

I have found that old 300-ohm twin-lead connectors, once used on TVs and 
FM radios, are the exact spacing for the sockets on the EC-1. I have 
been lucky enough to grub up 10 of them or so. Also, Pomona makes a 
mini-banana plug that fits the sockets well, it is part number 2945. 
You'll need 2 per component.

Cheers
