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.
[Demo] Eight Queen is a game written by Terry Smith and published in *Byte* Magazine, a well-known computer magazine that often featured software listings for readers to type into their computers. The game was designed for the Commodore PET, a popular early personal computer. The objective of the game is to solve the classic eight queens puzzle, where the player must place eight queens on a chessboard in such a way that no two queens threaten each other.
The game was likely distributed as a type-in program, a common practice at the time, where readers would manually enter the code published in the magazine into their computers to run the program. This approach was particularly popular in the late 1970s and early 1980s, when software distribution was limited, and magazines like *Byte* served as a key resource for hobbyists and programmers.
Terry Smith was known for creating educational and puzzle-based software, and [Demo] Eight Queen fits this category by challenging players to think strategically and logically. The game reflects the era's focus on programming and problem-solving, as well as the limitations of early personal computers, which often required users to engage directly with code. Specific details about the game's exact release date or additional features are not widely documented, but it remains a notable example of early computer gaming and programming culture.
