Hello,
Recently I wired up Jasons 4 in 1 Pac and I am having some problems perhaps someone here could offer a suggestion or two. First, the board ran absolutely 100% with regular Pac ROMs. After wiring the board and burning the 4 in 1 ROMS two problems exist. Game resets frequently on menu screen and either Pacman game and immediately resets as soon as I start either Ms Pacman game. I burned two sets of ROMS and the problem was consistant. I checked Mowerman's site and saw that chip 8B could cause frequent resets, after changing that chip there was no change in problem. Checked my wiring and all is correct. Sockets for daughter boards, Z80 and the 2 sockets for the hack have been replaced. Put Pac ROMS back in and board still runs perfect.
Anyone have any thoughts?
Thanks,
Rich
