Back when the A500 was more mainstream, there were many ram modifications (check Aminet). One of the coolest, which I did on the only computer I had at the time, was to swap in the 2Meg Agnes and put 2 Megs of ram directly on the motherboard. The memory in the trap door was disabled and useful only for the clock. If I recall, this mod was great but not compatible with the AdSpeed accelerator. I still have this machine.
