As far as computers... I punched cards and ran them on an IBM 1620. I think it must have had about 16 bytes of RAM... My favorite electronics catalog, of all time, the Dick Smith Electronics catalog. He was kind of like Radio Shack Down Under.
This cat was from Australia, and would pull advertising stunts like jumping a double decker bus over a row of motorcycles. Another time he charted a jet to fly over the South Pole.
Scattered in his catalog were some excellent Asian kits, all sorts of little projects. But the killer stuff... he had an ad for a Koatanga universal car antenna... it was really a coat hanger. Or a very heavy duty fuse, you just cut to length and it was blow proof... with a picture of a 16 d nail. Hah! I wonder if anyone actully bought the coathanger antenna or nail fuse? But it was very entertaining just to read.
