Emax

Just a note to let everyone know, you can upgrade the memory of your EmaxII by changing the EEprom.
I took the eeprom out of an 8 meg emaxII read it to a .bin file, and then burned the image to a new eeprom, then I fully populated the memory expansion board in my 4 meg machine and plugged in the new eeprom, and everything works perfectly. I also did images of 4mb and 6mb emaxII's and tested them with different configurations and everything seems to be working fine.
This will only work with 2 meg emax's, the original 1 meg emax's use different PALs, I could probably upgrade the 1 meg machines, but I would need the main board and expansion board to do it.
The biggest problem you will have is finding enough 44256 memory chips to populate the expansion board with.
I can supply the burned eeproms for $10 +shipping, if your not comfortable desoldering the old eeprom, I can do it for you, I don't need the whole machine, just the main board and expansion board, if interested, contact me off list.
