But there's already books out there, like the cmos cookbook, ttl cookbook, and an array of ttl/cmos manufacturers data books for pinouts.

I usually download everything from alldatasheet.com these days as a central supply of pinout info, they seem to have every chip i try.

I am however toying with the idea of compiling a databook for pinball chips & semis (trannies etc), since there's probably less than 50 chips across ALL pinballs, it might be a handy booklet to keep in the toolbox, rather than 10 differnet refbooks
