They're made by Sullins, and may be orderable from Digi-Key and other
of contacts. You
can also get it from Aklands Grainger.

Once the corrosion is removed I recommend using DC-4 on the connections. It
will protect the surfaces and keep great electrical connections. It is a
silicon grease that is non-conductive but keeps the surface clean and improves
metal to metal electrical contact. It doesn't allow oxides to build
DeOxit works pretty good for cleaning up connectors that still have serviceable
surface finishes, but yeah, temporary at best if the surface finish is gone. We
use it to clean up all sorts of connectors that are just regular dirty, pots,
etc.

I have DeOxit but I saw that as a very short term solution (no
pun intended :-)). I think I will try my idea of using solder
with a little silver in it if I can find some suitable.

Ah, yeah, if they're finished in matte tin or HASL, I just reflow leaded solder
on. A little bit of Superior #30 flux will make it flow

I am hoping to restore my TRS-80 Model-I(s). As is usually
the case with these the edge connectors are badly corroded
and dirty and cleaning them with an eraser really doesn't
