Changing the size of memory or changing the ROM version forces a reset of the PET.
The emulator has an IEEE-488 device at address 8. It can be used load and save (.prg) files.
Some programs don't run on ROM1 and some require more memory than the default 8K.
This bonus program reflects a bit of late night craziness. This program cycles through a bunch of pretend startup screens so you can try to trick your friends into thinking your PET boots up to development environments for Pascal, APL, or COBOL. These languages would all be supported for real by the SuperPET, a computer that would not be announced until May 1981, nearly a year and half after this program was written.
