Not to mention, if you start using log/alog tables, and/or sin/cos/tan
tables, and interpolation, you can quickly ramp up computation speed for
simple games that have a small matrix of coordinates. Something like
EMPIRE becomes quite easy.
Imagine my distress when, after cutting my teeth on a PDP-10, that
working on a 6502 I had to do my own division. Oh, the HORROR!
