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 program takes a list of words and builds a word-search puzzle, which is then sent to your printer. The intention is that you solve the puzzle the old-fashioned way—with a pencil (or a pen, for those who live life on the edge). While it's kind of neat to watch the PET generate the puzzle one word at a time, the title screen's warning that THIS PROGRAM NEEDS A PRINTER! is absolutely true—without a printer, there's not much to see here.
