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.
SHIP is an implementation of the classic board game Battleship that lets you play against a computer opponent. The computer is no slouch, either—expect a tough match. This version adds an additional wrinkle in that you fire a volley of shots, and the computer reports how many of them were successful, and which ship they hit, but leaves the results ambiguous enough that you will have to employ a bit of deductive reasoning to locate your quarry.
Sometimes the computer can be slow taking its turn, so it would be nice if there was some visual indication that it is considering its next moves. The first time there was a delay, I thought maybe the program had crashed. Aside from a bit of slowness, this is a solid version of Battleship.
