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!
