I was using one of these when I was 19. I wonder how many of you have used one, or even know what it is

About when I was ready to finish university, the first electronic calculator (Hewlett Packard, natch) was just coming out, but only the rich kids had them. Price was (keep in mind that this was in the 70's) close to $1000Cdn. Nowadays, calculators as capable are included as gifts in boxes of breakfast cereal. Cell phones, or something like them, existed only in Dick Tracey (there's another dated topic) cartoons.
