Hi folks
My wife got a Game King Video Poker machine (nickels) for x-mas and she would like for me to change some of the games and pay tables. I've done a bit of research and wanted to make sure I'm on the right track.
I've got quite a bit of tech experience (build servers and such) so the hardware part seems familiar. I know I will need a key chip, but I'm not sure which one or if that's the only chip I need. From what I've read, I'll be writing an EPROM with the new configuration. I've also attached a pic of the mother board (I think y'all need that to tell me what we've got and what we need)
I've downloaded what I think is the right maintenance manual, key-chip manual, and software manual. I've also got the pay tables figured out (I think).
Which keychip do I need to get and do I need to get anything else with it?
Anything else I missed?
