I used to play that in about the same timeframe. I
still have all of my
old RPG books, including G-W. They went through several major rule changes;
I think I have two of them.
I had Gamma World as well, but we thought it sucked. Shortly thereafter, I
got away from the whole gaming thing, as it just started getting silly
(i.e. Dungeons and Dragons characters became boring after just a few
levels).
Anyway, in addition to big computers, I collect:
1) Military Radios, specifically from the interwar period.
2) Navy transmitters, from 1945 and before.
3) Military Radars, tube based.
4) Military Sonars, tube based.
5) Tubes, all kinds.
6) Gyrocompass equipment.
and any day now, I wll loose control and start collecting:
A) Broadcast transmitters, from the 1920s and 30s.
B) Classic General Radio test equipment.
C) Railroad signalling junk.
