Yeah...I won't have to worry about that....PR2 aint gonna be my thing. Checked it out at Galloping Ghost, and will be just fine letting that one go.Those ram are also good for the namco boards system 11 / 12 they do die normally of rust / leg rot.
The other ram that may be needed is much harder to find: KM48V2104AT
8 is needed for the work ram, Mr Guru says there's no change to resistors / caps for that one but i'm still skeptical.
I would not worry about the work ram upgrade until PR2 is loading up to some extent in real hardware....
I know its a big deal for lots of other people though...so I hope parts can be sourced.
