Re: Tempest

Agreed, if you are having problems that are fixed by re-seating eproms
every month, then they have most likely lost or are loosing tension. Either
that or your sockets/ and or eprom legs are corroded or dirty.

I've personally not had any issues with the original gold double wipes, but
the single wipes they used suck and should always be-replaced.

As for which eproms contain game data, I think it's pretty much spread
through the majority of them.
