A Commodore 64 As You Have Never Seen One Before: Game Boy Form Factor!

It’s now nearly four decades since the iconic Commodore 64 8-bit computer saw the light of day, and the vintage format shows no sign of dying. Enthusiasts have produced all kinds of new takes on the platform, but it’s fair to say that most of them have concentrated on the original style keyboard console form factors. A completely different take on a Commodore 64 comes from [UNI64] in the form of the Handheld 64, a complete Commodore 64 in a Game Boy style form factor that uses the original 64 chipset.

It achieves this improbable feat by sandwiching together several PCBs, with a tactile switch keyboard and LCD display at the top. It appears to bring the 64 ports out to headers, and the ROM cartridge port to an edge connector socket at the top of the device. A departure from the 1980s comes in using a Raspberry Pi Zero to emulate a 1541 floppy drive though.

Sadly unlike a Game Boy there’s no onboard battery, but don’t let that take away from the quality of this feat. A forum post from [3D-vice] has a set of decent-quality pictures, and even if you don’t have a handy 64 chipset lying about we’re sure you’ll still appreciate them. If home made 64s are your thing, take a look at how you can build one without Commodore parts.

Thanks [pbuyle] for the tip!

  1. Nice achievement. A bit more practical thing to shoot for in the way of a portable Commodore 64 would be a laptop form factor using a modern color flat panel display. Would then be able to easily add modern lithium-ion battery pack to give it true portability

    Am thinking the Tandy Model 200 would make an excellent mid 80s retro laptop form factor to copy for such a project (which I happen to own a working Tandy Model 200 – too bad I lack all the other resources and skills to do such a project).

    Bought the Model 200 thinking one day might try to capture its case design in some 3D modeling software, but given that it still works, I didn’t have the heart to tear it all the way down to constituent components out of fear I might not be able to restore it back to working condition.

        1. Depends on which photo you are looking at. Link below shows an image of it where the keyboard looks more modern than the Model 200 one and the screen size looks to be nearly identical. The major key with the Commodore model is they were building all of their own components, including the LCD panel, so their price point could have been quite impressive. Shame they decided to build the C128 instead.


        2. Oh, I like the Model 200, no doubt, but I think if you are going to make a modern C64 portable getting your design cues from Commodore is the way to go, and the keyboard of the CLCD looks like it was made for the C64, just enlarge the monitor a little, ala Model 200. And as “Johnmichael Monteith” said, imagine Commodore made the CLCDm could have put them on a different track, imagine an Amiga laptop?

      1. Cute idea, but 20mA is nowhere near enough for the whole machine, you couldn’t power an atmega328p blinking an LED with that. Maybe you could use the extra current with a capacitor bank and a charge pump to recharge a secondary battery though

  2. I think this project was inspired by Chris Simpson (Perifractic’s Retro Recipes on YouTube) idea to make a handheld C64 after he picked up a Nintendo Switch.
