First on my bench will be a bunch (8 or so) of
Data General 800/1200
machines and a few Nova 2's. I can think of several questions so far
to get me started down the path:
1) A number of the 1200 machines have broken front panel toggle
switches (the switch handle was broken off and lost). Some are spring
return to center, some are just two position. Before I take the
approach of robbing one of the machines for front panel switches, is
there someplace that I can purchase exactly idential (both
electrically and cosmetically) switches, or does some one have donor
switches available for trade? I am a stickler for completely
identical parts, especially for front panel switches :) I was hoping
someone had been down this road before and knew the switch model #'s,
etc.
Jay, is this the front panel in the first picture on the wikipedia
page?

If those are 'standard size' mini-toggle switches, they may be C&K
switches (typically having a red body).
C&K switches tend to be well-marked with a type number stamped in the
metal, and are fairly prevalent in equipment from the period. I have
their catalog from the mid-70's with full listings. You might have
greater luck finding replacements by specifying the manufacturer &
type number.
(Sorry, looking at your message again I see you were asking for the
model #'s.)
If they are C&K switches:
The full catalog is there under "Download 7000 catalog pages". A
bazillion options.
