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.

n BETS you play a game of Blind Man's Bluff against three random players drawn from a pool of six. Each computer player has its own betting strategy. The PETSCII people are well-drawn and each has their own distinct look. The game plays well but I think it loses something as a computer game. A big part of playing in real life with actual human players is that you can try to use their body language to improve your betting chances.
