Save our High Scores

Save Our High Scores

S.O.H.S or Save Our High Scores 

In an attempt to keep our beloved scores forever, or at least a long time, I've started modifying program ROMs and adding Non-volatile memory to allow certain games to keep the score.

Bootlegz !!

"bootleg"/Clone PCB's

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.


Obsolete ICs

Antique DataSheets

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