I have one of those MV-1B boards that is for the Irritating Maze only (it's got that Saurus bios). From discussion on the other boards here, I realize there is a fix for that. How much would it cost to do this?
I can wire a socket on it to put a DIP style rom in, which I would then put in a normal 1-slot bios -- this is what I just did for a guy named Mike who got a 1B from NGF (sold to him as a *normal* MVS unit.
I was unable to locate an SOP style eprom (not even from SNK!!), so I couldn't do an exact chip replacement.
Hopefully in the near future someone will be able to supply me with a couple eproms that are the right size, then there will be no need to wire in a socket.
I charged Mike $25 to do the work, plus $7 return shipping.
