Game input holds PET matrix keys down until you physically release them, which is best for arcade games. Type input keeps the original short-tap queue for entering BASIC commands.
Charset Auto lets PET software switch normally. Graphics or Business forces the selected character ROM for compatibility/testing.
Changing RAM or ROM resets the PET. Some programs need ROM2/ROM4 or 16K/32K.
The sound slider controls the emulated PET VIA speaker. Modern browsers require a click before audio can start, so Start Game also enables audio.
The emulator has an IEEE-488 device at address 8 for loading/saving .prg files. D64 disk images can also be inspected for PRG files.

Game Notes
As of the current knowledge cutoff in October 2023, there is no widely documented or verified information about a game titled *Abacus* written by an unknown author and published by an unknown entity for the Commodore PET. The Commodore PET (Personal Electronic Transactor) was a popular early personal computer released in the late 1970s, and many games were developed for it, often by hobbyists or small teams. However, *Abacus* does not appear in major archives, databases, or historical records related to Commodore PET software.If *Abacus* exists, it may be an obscure or rare title that has not been preserved or documented in publicly accessible sources. Many early computer games, especially those created by independent developers, were distributed in limited quantities or through informal channels, making them difficult to trace today. Without additional details, such as a release year, publisher, or screenshots, it is challenging to confirm the existence of this specific game.
