2M Chipram is a bit more complicated, because the Agnus has a different pinout, and memory must be installed in addition to what's already there on the board. If you're a solder expert, you might be able to do it within a full working day, but I consider that very risky if you don't have a verified design on a known-good expansion board (aka 2M Chipram expansion for the Agnus socket).
I've already got 1mb chip using the ACA500 but i'm going to cheat and try and get an A500+ with an A501+ to get 2mb chip, I assume this will work with the ACA500+ACA1232?
