I have a dual monitor playchoice 10 pcb that needs a little help. Anyone out there work on these? Lmk
Thanks james
 
It's really weird, it plays some small cartridges fine but the larger ones have problems. It's a dual monitor and it will list the title of the larger carts on the top screen, you can select the game but once at the title screen the game will not start. Some of the games will also have some scrambled graphics.
Power supply has been verified good and games have been tested in another machine. I have tried one cart at a time and moved them into other slots. It's almost like it's having an address problem with some carts?
Games that work are Mario Bros, excite bike, Hogan's alley and duck hunt. TMNT, Mike tyson, gauntlet, will not work.

Any ideas? Lmk
Thanks james
 
Boy it sounds like it could be a program ram issue. Perhaps the smaller games only use a small portion of the ram while the larger games use more. Once the program execution gets to that problematic section of memory the game gets lost.
