One of 1977's founding trio of personal computers, alongside the Apple II and TRS-80 — an all-in-one with monitor, cassette deck and a notorious flat chiclet keyboard. It went into schools and small offices and taught a generation to program in BASIC.

Its games were terse character-graphics affairs: a homemade Space Invaders, chess, an early port of Rogue.

Why it mattered

One of the three machines that opened the personal-computer era in 1977, the PET put computing into schools and small businesses and set Commodore on the path to the VIC-20 and C64.

Emulating it today

Setup effortTrivial to run (1 on this site's scale)
ControlsThis is a computer-like platform: games may use a joystick or pad, but launching and configuring software often needs a keyboard.
Runs on a handheldYes

The emulator names above are starting points, not a promise that every title or accessory behaves identically. Computer platforms usually add model selection, disk handling and keyboard setup even when CPU emulation itself is mature.

Firmware

This system needs no firmware file. Install an emulator, open a game, and it runs.

How many files you need: none to go and find. No separate firmware file is needed for an ordinary setup.

Firmware details checked 2026-08. Emulator requirements change — see Libretro documentation for the current list.

Where the software is

TOSEC catalogues computer disks and tapes broadly, including many revisions. It is useful for preservation, while a smaller curated selection is usually easier to play.

This site names preservation projects and explains what they are. It does not link to ROM downloads.

Where to start

  3. Rogue 1980 RPG

The verdict

A foundational machine to explore for its place in history; its games are primitive.

The library is terse character-graphics fare — come for the history, not for an evening's play.

Worth it if
Players curious about commodore 8-bit home computers and willing to learn how the original machine worked.
Not for
Anyone who wants a large, instantly accessible library and no model, firmware or control decisions.

Scored 3/5 for fun today and 3/5 for historical importance. Those two scores decide the label at the top — a machine can matter enormously and still be no fun.
