The initial list credits would go to Stiletto going back to December 2010 when MAMEdev member Juergen B. was asking about available schematics for non-cpu videogames back then and then I added my share of info to Stiletto's list in that same thread. And I have been updating it since.
The list is a bare minimum since this only covers what is accounted for in preservationist hands. There are hundreds of other non-cpu games videogames not on this list.
