Every item is for either your Commodore PET, VIC-20, C64, C64c, SX-64, C16, Plus/4, C128 or C128D. Every product is currently commercially available or coming soon. That means that while you browse this guide, if you see something cool you can order it and have one for yourself.
The items are grouped into 12 broad categories and subgrouped thematically to help you find that expansion for your Commodore 8-bit that you never even knew existed, without first needing to know who makes or sells it.
Some items have feature pages, and more feature pages will be added over time. A feature page describes the primary function and use of the product, shows up-close photographs, lists the models of Commodore it is compatible with and links to the product's homepage and documentation. It also lists prices and gives clear instructions about how you can order it. The feature pages open up comments for the community to leave reviews, and to ask and answer questions.
TeensyROM is a ROM emulator, fast loader, MIDI and Internet cartridge for the Commodore 64/128 based on the Teensy v4.1 microcontroller board. TeensyROM now supports an NFC Loading System. Just tap an NFC tag on a reader to start any program. Designed with medium soldering skills in mind.
Load disk images, PRGs, P00s, CRTs from flash drive, on-board flash storage, microSD card, or across the network. Plug a MIDI device into the USB port and play your SID chip in realtime; works with many composition and sequencing packages. Works with modern Commodore networking software, emulates a modem for terminal emulators. Configuration stored in on-board non-volatile storage.
The BackBit Pro Cartridge is a universal instant loading cartridge capable of interfacing with a multitude of vintage computers and game consoles via proprietary adapters, including:
- Apple II+/IIe/IIgs Slot
- Atari 8-bits
- Commodore 8-bits
Supports most, if not all, original cartridge-based titles for each machine, and additionally supports tape, disk, and RAM expansion for a limited number of systems. Capable of supporting most modern homebrews. Bankswitching schemes up to 1MB in size can be implemented for nearly all platforms (if they aren’t already). Flash saving support can often be implemented. Special coprocessors can sometimes be implemented. Some adapters feature additional hardware for various things, such as audio emulation, copy protection bypass, joystick plugs, reset support, and more!
Loading is always instant. No need to take a coffee break while your program is loading. Built-in versioning system preserves your original files (on systems/configurations that support saving). Supports cartridge images up to 1MB in size. Real-time-clock. One-button diagnostic mode helps you identify system faults (on most systems).
An FPGA powered hardware platform for emulating the MOS 6581 and 8580 SID chips. It is a fully functional device that can be installed into a Commodore computer as a pin-compatible replacement.
This guy reverse engineers the motherboards of classic computers (Commodore, Amiga, BBC, Amstrad) and their peripherals (1541, Vidiot) and makes brand-new implementations of the boards to replace failed ones. For some you can even buy matching part kits. You're pretty much on your own for most ICs, though.
This book takes a single line of code—the extremely concise BASIC program for the Commodore 64 inscribed in the title—and uses it as a lens through which to consider the phenomenon of creative computing and the way computer programs exist in culture. The authors of this collaboratively written book treat code not as merely functional but as a text—in the case of 10 PRINT, a text that appeared in many different printed sources—that yields a story about its making, its purpose, its assumptions, and more. They consider randomness and regularity in computing and art, the maze in culture, the popular BASIC programming language, and the highly influential Commodore 64 computer.

The Brewing Academy LLC is located in Woodland, California, USA near Sacramento. We have been in Woodland since 2015 and have been operating in one form or another since 2005. In the past, we noticed that a lot of cool stuff came out for the Atari and the TI 99/4a and the Commodore, but that it always disappeared after awhile making it incredibly frustrating AND expensive for people to use their older computers. So, we decided to change that1 Our belief is that we find the coolest retro stuff we can and make sure we keep it available as long as possible.
This section of the "FujiNetWiFi" Git project contains applications, demos, and sample programs for the #FujiNet device. Some applications are generic terminals, for connecting to servers (e.g., netcat and PLATO). Others are clients for talking to standard online services (like twitter and iss-tracker), or #FujiNet-specific services (like apod and news; code for some of those live at https://github.com/FujiNetWIFI/servers). Finally, others are apps or demos that exercise other parts of the #FujiNet device (e.g., appkey-sample and LiteSAM).
Generally, compiled executable programs are likely to work best if you disable built-in BASIC while booting your Atari (hold [OPTION] on XL and XE models).
An interesting operating system with file system compatibility to CP/M-80 (and other similarities).
"What I (Richard A. Leary) have done is attack the software side of the problem in order to make any 6502 system a truly workable disk based system. In addition a degree of compatibility is now possible not only between 6502 systems but with large parts of the world of CP/M systems. The result of my efforts is a system of software which I have named DOS/65."
Sells storage adapters, upgrades, and accessories for classic 8-bit computers, including the Atari and Commodore.
Lotharek sells hardware upgrades and replacement parts for retrocomputers, including the Commodore and Atari 8-bits.
The Transactor was started life in 1978 as a Commodore Business Machines publication used to explain low level details of the Commodore PET. In 1982 it was reborn as a bimonthly independent magazine published out of Milton Ontario (Toronto) covering all 8bit Commodore’s. This revised magazine used the slogan new slogan was “The Tech News Journal for Commodore Computers” and was paid for through advertising and subscription prices. A quick scan of the covers below and you will be able to see when this change occurred. The Commodore Transactors were mass produced using a very inexpensive mimeograph technology while the independent magazine was created using a proper printing press.
Both publications were known for their depth. They covered hardware hacking in detail and were read by serious users. One issue even boasted that it was 95% advertising free right on the cover.
Cases and replacement parts for Amiga computers. The cases even have mountpoints for popular aftermarket hardware upgrades, and even a RasPi 3 or 4 if you just want the shell!
If you have an interest in the Commodore 64 (C64), SX-64 and Commodore 128 (C128) and all the various hardware that comes with that, like 1541 disk drives, modems, 1702 monitors, etc, then the Commodore Computer Club and Users Group is for you.
We also discuss the Commodore Amiga, VIC-20, Commodore 16 (C16), Plus/4, CBM PET and even the C64 Direct-to-TV (C64DTV) designed by Jeri Ellsworth. If it’s Commodore related, we discuss it at our meetings.
The goal of the club is to have monthly meetings and discuss cool things that are still happening in the scene as well as share project ideas or concepts and to inspire each other for new ones.
In May of 2011 we started the Retro Computing Club as a “sister” club to compliment and cover other vintage computers like Apple, Atari, IBM PC, Tandy, Texas Instruments, Macintosh and more along with video game consoles like Nintendo, Vectrex, Sega, etc.
Like any self-respecting user group, their resources page is well populated.
Atari 8 bit computers, NES and SMS game consoles on your TV with nothing more than a ESP32 and a sense of nostalgia. Simple schematic to rig up video and audio outputs to connect to a television.
Emulates the Atari 400/800, XL, XEGS, 5200, NES, Sega Master System, and Game Gear. Controllers and keyboards must be Bluetooth enabled so that they can connect to the ESP32.
Most interestingly, it has an HTML-with-Javascript page (https://github.com/rossumur/esp_8_bit/blob/master/atr_image_explorer.htm) that stands alone which implements a drag-and-drop .atr image explorer/binary disassembler.
Win 7/8/10, and Linux/i386/AMD64 kernel driver and development library to control serial CBM devices, such as the Commodore 1541 disk drive, connected to the PC's parallel port via a XM1541 or XA1541 cable. Fast disk copier included. Successor of cbm4linux. Also supports the XU1541 and the XUM1541 devices (a.k.a. "ZoomFloppy").
OpenCBM provides an interface to the Commodore IEC bus at the level of simple TALK and LISTEN commands, similar to the one provided by the Commodore kernel routines. Additionally, some higher and lower level bus control is available as well, allowing for full control of the bus.
The CBM serial devices are connected to the PC either to the parallel port via an XM1541 or XA1541 cable and, optionally, an XP1541 or XP1571 add-on cable. Alternatively, more modern USB cable solutions like XU1541 or XUM1541 (a.k.a. ZoomFloppy) are supported.
Any Linux, FreeBSD or MacOS X variant that support libusb-1.0 should be supported. Linux, FreeBSD and Mac OS X have been explicitly tested.
