Canonical List of Commodore Products: This list contains informations on every piece of Commodore equipment I have heard of to date. Please help me weed out all the inconsistencies and nail down all the information. This list was originally conceived and created by Jim Brain. It is now maintained by Bo Zimmerman.
Cassiopei: To make a long story short, the Cassiopei (which stands for CASSette IO Peripheral Expansion Interface) is a device that connects to the cassetteport of your CBM computer. Although it can playback .TAP files and act like a datasette… it is much more then your ordinary digital tape player! One key aspect is that the Cassiopei can also playback .PRG files and it can load them 50x faster then Commodore's standard tape loading protocol.
CBM Tape Pi: Use a Raspberry Pi as datassette drive with your Commodore 8-bit computer!
CBM-HD: CBM-HD is a project where a PC simulates one or more IEEE devices. If you are familiar with 64HDD, a PC simulating a 1541 drive, then you can consider CBM-HD as its IEEE equivalent.
CBM-Transfer: CBM-Transfer is a front-end to several command-line utilities for transferring files and working with disk images. CBM-Transfer makes using those utilities easy by providing a familiar windows interface that removes the need to learn the commandline syntax of each program. CBM-Transfer also includes a multi-format file and picture viewer.

Cute32: Cute32 is a fully featured tool that allows archival and replay of all tapes designed for CBM 8-bits machines (Commodore 64, VIC-20, PET, Plus4, C16 etc). CUTE32 is able to completely and accurately emulate a Commodore Tape recorder C2N 1530-1531 in all of its functionalities but, unlike the original tape recorder CUTE32 takes advantage of digital file storage on Micro SD cards to archive the original magnetic tape content. This prevents data losses due to wear-and-tear that are very common when using cassette tapes to store digital information. CUTE32 comes in a high-quality box that reproduces (smaller scale) an original Commodore Tape recorder.
DC2N: The DC2N can be used for three purposes: make backups of PET, Commodore 64/128, Vic20, C16/+4, Spectrum, BBC, MSX, and Spectravideo tapes (including using both signal edges, a.k.a. halfwaves); record from a PET, C64/128, VIC20 (with a third party adapter C16 is supported as well); and playback v0 and v1 TAP files to PET, C64/128, VIC20 (with a third party adapter C16 is supported as well).
OpenCBM: 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”).

Die Entwicklung ist ein Universal-Chip, der nicht nur in einem C64, sondern in neun verschiedenen Geräten eingesetzt werden kann. Die Einstellung dazu erfolgt mittels DIP-Schaltern.
Retro Commodore: Your place with high quality scans for preservation.
SSSSAM: Text-to-speech for the Commodore computer. If you owned a C64, an Atari or an Apple computer, then you might be familiar with the synthetic sound of the voice of SAM. The Software based text-to-speech speech synthesizer package that required no additional hardware. But if back then, you only had a VIC-20 then you missed out, because SAM won't run on such a system, there simply aren't enough resources, since the VIC-20 doesn't have enough RAM. But the project on this page is about SAM and this project does work perfectly fine on a VIC-20 (and also on various other Commodore computers that have a userport).
Style: We make demos, tools, and toys for your Commodore Business Machine.
TEDuino: A Modern TED (264) Series Commodore Datasette. For this project I use another Arduino, in this case the inexpensive Arduino Nano version, some easy to source electronic components, and a 3D printer to create a Commodore 264 series inspired Datasette replacement I call, the TEDuino.
The Commodore Knowledge Base: The Commodore Knowledge Base is an assimilation of various articles on Commodore repair, programming and technical issues, ranging from beginner level to advanced, covering a diverse series of topics from CP/M to hardware modifications. CKB covers the gamut of Commodore 8-bit systems, not Amiga and very little on the PC series. Emulator content is intentionally limited, although cross-platform development is a considered topic. CKB articles originate from many sources, largely the Usenet group comp.sys.cbm, patrolled by a news robot maintained by Cameron Kaiser. Kurt Brandon has also provided a significant number of articles gleaned from BBSes and the now defunct QLink online service. Other notable contributors include: Marko Mäkelä, Stephen Judd, John Iannetta, Doug Cotton, Nicolas Welte, Jim Butterfield, Jim Brain, Ray Carlsen.
The Future was 8bit - SD2IEC: Of all the methods of loading stuff into your Commodore, TFW8b's SD2IEC SD card interfaces are the business. SD2IEC provides much of the functionally a 1541 disk drive, supports fast loaders like JiffyDos, Final Cartridge III and Epyx FastLoad. TFW8b.com version of the SD2IEC is the most common method of loading/saving on a Commodore 8bit Today!
The Secret Weapons of Commodore!: They were the secret weapons! The unrealized phantasms of technological wonder! The ravings of mad geniuses made flesh and locked away in caverns of dust never to see the light of day! The demons that Tramiel forgot, to come tapping at their door even as the winds of oblivion beckon and spit!
Uno2iec: A commodore (CBM) 1541 emulator on the Arduino Uno, using any desktop PC (or raspberry PI with raspbian) as a media host. The UNO2IEC device simulates a 1541 drive and enables loading and saving files or programs between a CBM and any “current” folder on the host system. The host system location can be a network share, an USB or SD flash media, SSD or any hard disk that is supported by a Windows, Linux or Mac operating systems.
ADF-Copy: ADF-Copy is a small hardware i developed which uses a Teensy 3.2 microcontroller to read and write non copy protected Amiga disks with an out of the box PC 3.5″ Floppy drive connected to the microcontroller which can be build with a few jumper wires on a breadboard with no additional component. The low level stuff is handled in the microcontroller which is controlled by a Java application.
A.D.A. Amiga Demoscene Archive: On the Amiga Demoscene Archive, you will find some of the best demos and intros released on the Amiga.
A314: The A314 is an expansion board for the Amiga 500 that goes in the trapdoor expansion slot. A Raspberry Pi (RPi) is attached to the A314, and the A500 and the RPi can communicate through a shared memory. We have constructed a communication protocol through which associated processes on each platform (Amiga and RPi) can allocate logical channels, carried over one physical SPI channel. The protocol is handled by a driver on each side (a314.device on the Amiga and a314d on the RPi). The drivers are responsible for alerting receiving processes of incoming data via an interrupt.

AMIGA 500 - SWITCHLESS BOOT SELECTOR (3 RESET BOOT DRIVE SELECTOR): “A500 - Switchless Booter” is a circuit for changing boot priority of floppy drives, for Amiga 500. If you use a second floppy drive connected to your A500, like GOTEK Drive or a mechanical floppy drive, (as DF:1), then you need a boot selector to boot from the second drive. (Most of old boot selectors work with a toggle switch.)
Amiga-Digital-Video: Add pixel-perfect HDMI output to the Amiga machines. For all Amiga versions that have a socketed DIP Denise chip, a rather small adapter board can be used to extract the digital video signal (12 bit) to a 40-pin connector compatible with the Raspberry Pi Zero. This can then be used with the RGBtoHDMI software to produce a perfect HDMI picture with very low latency (a few milliseconds at most).

Big Book of Amiga Hardware: The Big Book of Amiga Hardware is probably the largest online Amiga Hardware reference in the world, thanks to the help of many of the site's readers. If you're looking for information on that exclusive piece of hardware, wonder what amazing expansions were actually made for the amiga, or need drivers for that second-hand kit you've just bought, then you've come to the right place.
Cracktros: Welcome to definitive AMIGA Cracktro page on the internet. Here you'll find the ultimate collection of AMIGA Cracktros and Trainers.
DiagROM: DiagROM is a diagnostic tool for the amiga computers. And it is to be used on defective machines, trying to help no-boot situations etc. You simply replace the Kickstart roms in the Amiga with the DiagROM. and when poweron. your Amiga will start a diagnostic software. It will try to dump info on the serialport (and actual menus etc aswell) while also trying on the screen. One important thing is that the software relies on as little hardware as possible. so no timers, no IRQ etc. so you can start up the machine on a very broke machine and from that test different things. and hopefully help finding hardwareissues.

PiStorm: The PiStorm itself is an adapter board intended to be paired with a Raspberry Pi Model 3A+. It goes in the DIP socket on and acts in place of the CPU, but functionality can be extended beyond simple CPU emulation. While the PiStorm should work with any DIP socket 16-bit 68000-powered system, the FC lines are currently not properly handled and no guarantees can be made for it working on anything except an Amiga 500, 500+ and 2000. General Performance with the current use of Musashi as the 68k CPU emulator is somewhere around a 70-80 MHz 68030.
The Amiga 1000 Parceiro: The Parceiro (sounds like par-say-ro) attaches to the side expansion port of the Amiga and is about the size of a harmonica that’s been run over by a steam roller as it’s only about 1/3 of an inch thick. It provides the following features: 8MB of Autoconfig Fast RAM. It is a single 8MB of SRAM versus DRAM, so it really and truly is indeed fast with zero wait states - Coin-cell battery backed Real Time Clock (RTC), which comes with its own clock software that gets put into your startup sequence - SD Card Reader with 2GB MicroSD. It comes pre-formatted with the FAT32 file system and is readable on any PC as a result. This way you can quickly set up your new SD-based hard drive. It’s worth mentioning that this is running on period correct Amiga OS 1.3, too.
ZoomFloppy: ZoomFloppy brings Commodore disk archival into the 21st Century, bridging the gap between the both the IEEE-488 and IEC-based disk intelligent Commodore™ disk drive line and contemporary personal computers. Taking up the baton from the ever-popular X*-1541 line of parallel port interfaces, ZoomFloppy provides complete functionality for newer machines running multitasking and multi-user operating systems and those systems lacking the legacy parallel port upon which the X*-1541 interfaces depend.
Commodore 128 40/80 Column Video Adapter: I was looking for a solution to be able to display 80 column video of my C128 onto my TV in color. Various schematics were out there, but all had different drawbacks. So I decided to encorporate them all into one design, thus creating the Commodore 128 40/80 Column Video Adapter.
1541 Diagnostic Cartridge - World of Jani: I have repaired a fair amount of drives, and every time I find myself loading a test or a diagnostic software from disk. This is a bit of a contradiction since the drive being tested, or repaired, might not even be able to load a program. I also have a variety of tools for different purposes and wanted to have everything in one place. This is why i created a 1541 Diagnostic Cartridge.
1541 Ultimate-II: The '1541 Ultimate' is a storage solution for your Commodore C64 and C128 home computer. This piece of hardware implements a 'real' 1541 diskdrive for Commodore computers. There are two versions of this board; the 1541 Ultimate-I and the 1541 Ultimate-II. The 1541 Ultimate-I uses an SD-card or MMC-card to store the floppy disks, while the 1541 Ultimate-II uses MicroSD and USB pen-drives. Both the 1541 Ultimate-I and the 1541 Ultimate-II contain a replica of all the necessary hardware to be fully compatible with a real drive.

Commodore 64 Guides: Having recently returned my Breadbin to perfect working order, I also wanted brand new copies of the C64 User’s Guide, and Programmer’s Reference Guide to complete the set. I could have simply printed one of the scans of these guides from the internet but where is the fun in that? In truth, I have found all these scans somewhat disappointing - very often indistinct and not always complete. Instead, I did the only sensible option: I re-wrote them from scratch using my copies of the originals as source. I reconstructed every graphic (including front and back covers), every register map, every block diagram, every table and every paragraph to have a pristine final result.

OpenC64Cart16K: OpenC64Cart16K is an Open Hardware Cartridge for the Commodore 64. It only supports 16 KB ROMs and uses a single (E)EPROM chip.
PLA16V8: The PLA16V8 is a GAL PLA replacement for the Commodore TED series computers (such as the Commodore 16, 116 and Plus/4) that I did design after the succes of the PLA20V8. In a TED based computer, the most common point of failure is the 8501 CPU. Therefore the shortage of PLAs is not as severe as for the Commodore TED computers, it is easier to find an original PLA than for the Commodore 64. That said, the PLA in the Commodore TED series computers can fail and you may want to replace it with a more available component. This is now available. the PLA16V8 is ready to service you!
PLA20V8: The PLA20V8 is a PLA that consists of two GAL20V8B chips from Lattice Semiconductor. The GAL is a programmable logic chip that looks a lot like the original PLA: It has an AND array, followed by an OR array. Depending on the mode of the GAL the signal then can go through a flip-flop, which the PLA does not have, but this flip-flop is bypassed in the so called “simple” and “complex” modes, which makes the chips rather close to a PLA, perhaps the closest possible chips to a PLA you can get. We need two GALs, because we can't fit all the logic in a single GAL.
Ray Carlsen's Home Page: This site is dedicated to users of 8 bit Commodore Computer hardware. The information herein is listed in “directories”.

The Pictorial C64 Fault Guide: This guide lists pictures of various Commodore 64 problem scenarios along with their descriptions and known causes. Use it as a tool to assist in diagnosing C64 issues, to get a general idea of what might be wrong with your machine. Keep in mind that it's rare to find an exact match and sometimes multiple different problems can cause a similar faulty screen. This site focuses on the classic breadbin models, though many of the fault scenarios are also applicable to newer revisions such as the C64C.
The Ultimate Tape Archive (C64): Welcome to the most complete Commodore 64 cassette archive that exists. By complete, we do not mean it's all the titles ever made, but all tapes are complete with coverscans and manuals all in one place for you to enjoy.

Ultimate-II+ - Ultimate 64: Back in 2008, the idea came up to create a cycle exact floppy disk drive emulation of the Commodore 1541 drive, and embed this emulated drive in a cartridge for the Commodore 64 home computer. Today, the 1541 Ultimate and related products have become indispensable extensions for the Commodore 64 and 128 computers. According to some users, it has completely changed the way they use the old machine as it nearly eliminated the need for real floppy disks.
Versa64Cart: Versa64Cart is designed to be a modern easy-to-use cartridge development board for Commodore 64 and Commodore 128 hobbyists and hackers. The versatile design of the PCB allows for flexible implementation of various cartridge types. Whether it’s a simple cartridge backup of an 8k game or a switchable multi-program diagnostic cartridge, Versa64Cart has you covered.
VICII-Kawari: VICII-Kawari is my hardware replacement project for the VIC-II (Video Interface Chip II) found in Commodore 64 home computers. In addition to being compatible with the original VIC-II 6567/6569 chips, some extra features will also be available. The PCB will interface with a real C64 address and data bus through the VIC-II socket on a C64 motherboard. The board can replace all the functions of a real VIC-II chip including DRAM refresh, light pen interrupts, PHI2 clock source for the CPU and, of course, video output. (NOTE: Light pens would only work on a real CRT using composite.)

VIC-20 Listings: VIC-20 Listings is an archive of type-in games, utilities and other programs for the Commodore VIC-20 home computer, that were published in various books and magazines during the 1980s. These programs are often overlooked or missing from other collections of retro computer software. There are currently 2,468 programs in the collection. The aim is to make each program available for download together with details of who wrote it, where the listing was published, any special requirements, and brief instructions. Each program is kept as close to the original listing as possible.
VIC Term 300: VICTerm300 is an ASCII Terminal emulator for Commodore VIC-20, written in BASIC so it can run just at 300/600 baud. It's just a slight improvement to a BASIC demo program printed on the VIC-Modem guide.
