The only think that I don't know is wether it supported both addresses (for Chip
and "Ranger" mem).
IIRC that depends on the A500 model (A500 it was "slow/Ranger mem, on a A500+ it was chip).. However I recall it was either 512K Mem and 512K ramdisk or 1Mb Chip or something also depending on the model/chipset....
