I'll give you a general overview of the '90s rules.

You were limited to the KOP, a certain amount of raw material, and $X from Small Parts Inc. The KOP contained such items as a cordless drill, a dot-matrix printer (1992), and some other stuff of that nature, depending on the year.

Exactly what the raw material amounts were and what the cool stuff for you to take apart was depended on the year. The rules opened up around 2000, IIRC, and then some more later.
