A500s and A2000s are designed to accept a pin-compatible 512K ROM.  The main
reason for NOT building a 512K ROM today is the extra trouble A1000 owners
would have, I suspect.  Beyond 512K, you run out of address lines on the
physical ROM and address space to put it in, so today's machines are basically
limited to 512K.
