Title: Classic Nintendo Arcade games Post by: jtdollard on February 04, 2013, 11:53:15 am Ok so I traded a guy in my town a working SMB for a Working Hogans Ally and 4 nonworking(untested) boards that he got in a large lot that came up for sale in here in Nashville last week. So the boards are DKJr, DK3, Popeye, and Mario Bros. They are all missing there EPROMs and most of the socketed chips but other wise look clean no on the surface problems. So my first goal is getting the DK3 working I know it needs 2 RP2A03 CPUs like the ones on the Vs boards and I have a few of those so no problem there (But if any one has to many of them I would be glad to ease you burden just PM me ;D) What i need is to know what type of EPROMs this board uses and what the chips at 6 B&C on the CPU board are so i can replace them. I am also needing the same info on the other boards EPROMs and any other socketed ICs.

Now my question is Does anyone know If there is any thing special about these Z80A's or will ones like these work?
