Hi Do you have a Rev 1 digital board?
If so it might be an easy fix to get it to an EII +.
If you look at the digital board where the memory is it will have jumper locations labeled for 256K and 64K.
Good news is if you set the jumpers to 256k settings and put in 256K memory dram in the locations on the main digital board and replace the main and scanner eproms with + versions you should then have an EII+
The plus models didn't use the piggyback memory board.
Hope this helps
Hey thanks for the help! I have a Rev 1 board. Did you get yours to work?
