Testimonials
I have used C64 OS literally every day since I received it, even if it was just to turn on my C64 and see it load, and it brings a smile to my face that it exists every time! 😊
The app launcher itself has definitely proved to be something that makes it significantly easier for me to use my C64 for finding and running various applications in my day, where often my time at my desk is limited. Thank you again! Adam K0FFY — November 2022 — X (Twitter) DM
C64 OS is the perfect blend of modern OS concepts with mechanical sympathy for the classic Commodore 64! It has truly rekindled my interest in the design and implementation of computer operating systems. Not only that, it's an absolute delight to use, and sometimes fools you into thinking you're working on a machine designed this millennium!
But wait, there's more! If you want to write software for your Commodore 64, C64 OS does almost all of the heavy lifting for you! A comprehensive KERNAL API, object-oriented programming, and a UI Toolkit inspired by OpenStep all combine to make 6502 assembly language application development a dream!

C64 OS Reviews and Unboxings
Reviews are different from demos. In the demos above, C64 OS is presented on a tight schedule with a prepared set of talking points to move quickly and show off the latest key features and abilities.
In a review or an unboxing, the host may be trying out C64 OS for the very first time, and is not an experienced C64 OS user who knows all the tricks and shortcuts. Therefore, reviews are a sort of adventure, exploring novelty and discovering what might be found. Some things mentioned may be slightly inaccurate and the hardware upon which the review is being run may be slower or less powerful than other possible hardware combinations.

C64 OS + Hardware Collections
New software, new hardware, all new capabilities.
A C64 fan's dream come true.
The following hardware collections are a sample from a myriad of possible combinations. They give a broad overview of the progression from the simplest and least expensive way to get more out of your C64 by running C64 OS, to the more advanced and modern collections that look fantastic and also offer the most powerful opportunities for C64 OS to take advantage of.
Barebones Collection
- A C64 Breadbin
- A Joystick
- An SD2IEC
- And C64 OS
The only new kit needed is an SD2IEC—these come in a multitude of form factors, some cost as little as $45 USD—and that's all you need to get into C64 OS.
Explorer Collection
- A C64 Breadbin
- A 1351 Mouse
- An SD2IEC
- And C64 OS
If you want to explore C64 OS further, the most obvious next step is to switch the joystick out for a mouse. If you can't find a 1351 there are many adapters for modern mice.
Hipster Collection
- A Commodore 64c
- A 1351 Mouse
- A Cableless SD2IEC
- And C64 OS
Step up to the sleeker C64c but keep the 1351 for that retro hipster feel. A cableless SD2IEC eliminates the serial cable for a tighter more modern look.
Serious Collection
- A Commodore 64c
- A 1351 Mouse
- The JiffyDOS KERNAL
- A Cableless SD2IEC
- And C64 OS
If you want to get serious about using your C64 with C64 OS, upgrading your KERNAL ROM to JiffyDOS is the first best step.
Modern Collection
- An Ultimate 64
- A PS/2 or USB Mouse with adapter
- The JiffyDOS KERNAL
- A Cableless SD2IEC
- And C64 OS
The Ultimate64 takes a JiffyDOS ROM image, offers an RTC and a 16MB REU. Pair it with a cableless SD2IEC and a USB mouse and MouSTer for a modern C64 OS experience.
Network Collection
- An Ultimate 64
- A PS/2 or USB Mouse with adapter
- The JiffyDOS KERNAL
- A Link232 WiFi Cartridge
- A Cableless SD2IEC
- And C64 OS
Take the final step by adding a highspeed serial port with built-in TCP/IP WiFi modem, and your C64 is ready to follow C64 OS as it marches into the future.

New or returning to the Commodore 64?
