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.

Numpad + -Utility Auto Daten is a lesser-known game written by D.W. Engelfriet and published by Hans Metz, who were active in the early days of personal computing, particularly for the Commodore PET. The game was likely released in the late 1970s or early 1980s, during the peak of the Commodore PET's popularity. Hans Metz was a notable publisher of software for the Commodore PET, and D.W. Engelfriet was one of the programmers associated with this platform.
The exact gameplay mechanics and objectives of Utility Auto Daten are not well-documented, but it is presumed to be a utility or simulation-style game, given its title. The Commodore PET was primarily used for educational and business purposes, so games like this often had a practical or educational focus. The title Auto Daten suggests it may have involved data management or automation, possibly related to vehicle or automotive data, though this is speculative.
Unfortunately, due to the limited availability of historical records and the niche nature of early Commodore PET software, detailed information about Utility Auto Daten is scarce. It remains a piece of obscure computing history, primarily of interest to retro computing enthusiasts and collectors of vintage software.
