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.
Tower And Dragon is a classic dungeon crawling adventure with primary and offhand weapon, armor, quest storyline, moving walls, teleportation, and unique tilesets and monsters for each dungeon level. Your character starts out just after climbing down the stairs into an ancient ruin, discovered by following a dream. The game is a tribute to the game that inspired me to become a programmer: "Dungeon" from 1979. Like Dungeon, this game only requires 8K of memory".
