Backup ram error help me please

hello everybody.

someone can help me please ?




merci
thanks a lot

Looks like both backup ram chip are bad and in need of replacing. Try searching backup ram error in these forums...

perhaps only the 3.6v lithium battery ?
i don't see the same error code in this forum

Definitely not the battery because a working MVS board still works fine even without battery. It has to do with the ram chips. Check the area around them and the connections with the 68000. Probably both rams are bad and you'll have to replace them.

Or, you could replace your bios with Razoola's unibios that allows to skip the ram tests and boot the system so you'll be able to play the games.
