[GreenKeys] Fun rebuilding 33 keyboard

[Jones, Douglas W]

Thanks to Paul Cembura (Mr RTTY) for new keycaps and Wayne Durkee for
instructions, my students and I have replaced the cracked and crumbling
keycaps on our 33.  For a writeup and photos, see:

The new-old-stock keycaps Paul sent are pristine -- but just the caps,
not the keylevers.  Therefore, we had a bit of fun learning how to
extract keylevers from old keys, but we were entirely successful, and
many of the old keycaps were undamaged by the process -- we did smash
one old cap, and several of the badly cracked old caps came apart in
the process.

I do seek one bit of advice:  Can the old caps be polished to match
the nice shine of the new ones?  As things stand, the old caps are
a frosty grey color.  I tried solvent polishing them (Plastruct
Bondene solvent cement doesn't seem to do a thing for the key caps,
while it is an excellent cement for the ABS used on the Teletype
cover).  Any ideas?
