Wow Marty reading this tutorial took me back to the days when Dick Smith was selling heated toilet seats - anyone remember those?

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
MM.

What a great idea!!
