Re: Memory Upgrades

Alright everybody, I took the plunge... have at it.  I will upload the BIN to the files section.

EMAX II it came from:
Model 2213
SN: 01200659

Main Board: PC360 REV C
SN: 900428

Upgrade Board: PC357 REV B (fully loaded)

Hopefully someone can put this info to good use.  I have ordered a few 9346s and sockets.  I'd be glad to burn a few and send them out if someone needs them.
