S.O.H.S or Save Our High Scores

Bootleg/Clone Game boards

The bootleg, clone or copyboard, is a non-original copy of a gameboard. Sometimes they are exact duplicates of the original hardware or a totally different 'bootleg' board design.

I'm in the process of documenting a few of the bootlegs I've run into.

Antique DataSheets

Datasheets for some really ancient IC's, SRAM, EPROMs. Totally obsolete in modern times but used on plenty of older arcade boards.
