Yes, two wires, they run to the option RAMs, chip selects? Mailing list don't allow picts right?
I see the EME support files on the club100 site, I don't have a windows PC so I can't run the laptop.exe file, is it only used to load the extRAM Model 200 files? I could put the sleeve back together and load those files manually and see what happens. I'm probably missing it, but I don't see a manual or any support info on how to utilize/activate the extRAM module.
