Neo Geo, Backup RAM Error, dip switch 1 for service mode?
Hello everyone,
I just got my first neo geo and it's a bit of a project.
I tried registering on a forum dedicated to Neo Geo stuff, but while my account is activated I can't seem to post.
It's a 4 slot and throws an error on power on about the backup RAM being bad. WRITE AAAA READ AAAE. Checked the OE, CE and WE pins from the SRAMs on the board and the traces are good to other chips. Not sure if the one 32 DIP chip is good or bad.
The battery had not leaked, but I removed it anyways.
I read that changing the 1st dip switch to ON should throw the machine into a service menu where I should be able to access a page to blank the backup RAM. I tried both 1 on and all 8 switches on, but it still just comes up with that same backup ram error. Is this normal? I can't find a reference if the dip switch will force service menu when there is an error present.
TIA for any insight!
