Is there a way to change the ROM on a Commodore while it is running? I have an idea for using a large Flash ROM type device, but instead of a physical switch for changing ROM images, I want to make an internal IEC type device to change the ROM while the computer is running. In theory, this would let the ROM socket become a virtual storage device of a kind. The call to the IEC Device number would be able to switch ROMs on the fly allowing access to custom ROM routines from a much larger set of ROMs. In the case of a Flash device in place of the ROM, perhaps the IEC could also flash ROM slots. This of course requires the Commodores not having fit if the ROM content change. I would set the IEC device to a high number like 30 or 32 so it wouldn't interfere with normal IEC operation.
