OK cheers, I just stumbled upon an auction for another side car expansion (just waiting for the seller to confirm total RAM present on it) and that would give me 4 1/2 mb rather than 2.5mb I have now (only 2mb with KS2.0 softloaded)
I know 8mb is the theoretical limit due to the A500/2000 being limited to 8mb 16bit FAST RAM, wasn't sure why the A1000 never had a 2mb side expansion unit.
Let us know how it goes. Love a good piggy back. Seen some doctored A501s that did that at a mem chip level.
