The autostart can be defeated by an alternative KERNAL ROM, or with Markus
Brenner's dumping switch (his homepage was on Arnold, don't know if it's back
again). Sometimes I cover the EXROM line with a piece of tape plug the
cartridge into a C128. I can then read the contents from the built-in monitor.
