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.
Drag is a game written by Earl Furman and published by CodeWorks - Cursor, a company known for developing software for the Commodore PET, a popular early personal computer. The game was released during the late 1970s or early 1980s, a period when the Commodore PET was widely used in educational and home computing environments. CodeWorks - Cursor was one of the many small software companies that emerged during this era, creating games and utilities for the burgeoning personal computer market.
The specific gameplay mechanics and objectives of Drag are not well-documented in available historical records. However, given the context of the time and the type of games typically produced for the Commodore PET, it is likely that Drag was a simple, text-based or low-resolution graphical game, as the PET's hardware capabilities were limited compared to later systems. Games from this era often focused on basic concepts like racing, puzzles, or simple simulations, and Drag may have followed a similar design philosophy.
Earl Furman's contributions to the Commodore PET software library, including Drag, are part of the early history of computer gaming. While detailed information about the game is scarce, it represents the creativity and experimentation of early developers working within the constraints of early computing hardware. The legacy of games like Drag lies in their role as foundational pieces in the evolution of video games, paving the way for more complex and visually advanced titles in the years to come.
