I have the manual for PPI 68040 accelerator the 2000 ( sorry don't have it scaned). My book shows it can take either 4 megs in bank 1 ,8 megs in banks 1&2, 16 megs in bank 1,32 megs in banks 1&2.there are jumpers on the board to set memory config set to. I also have the install disk for it. It works great in my 2000 .
I will try to answer questions
