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.

64HDD: Have you ever wanted to give your old Commodore™ computers a hard drive, CD-ROM or access to the devices other modern computers have? 64HDD is software that lets you do just that, and much, much more.

C64 Modulator replacement: C64 Composite/S-Video RF Modulator Replacement. Based on the C64 RF-modulator mod by Zero-X / OMS, this adapts those schematics to create a complete replacement for the original modulator including a few changes of my own. A nice writeup and the my original inspiration for making this version if it came from a blog post on My Diy Blog (not actually my blog, it's just called that).

c64-rf-modulator-replacement: C64 Composite/S-Video RF Modulator Replacement. This is my version of a C64 RF Modulator replacement based on the schematics of similar designs like Zero-X/OMS's Modified Commodore RF Modulator Design and JMP$FCE2's S-Video only design. This board can be used to replace a damaged or defective RF modulator in your C64, to improve the sharpness of your video output, or as a modern solution to replace the composite/luma/chroma output functionality of the original modulator on new motherboards such as the SixtyClone or Bwack’s KU-14194.

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.

ReplayResources: Originally introduced by Datel Electronics the Action Replay and its' successors Retro Replay and 1541U have become indispensable tools to the C64 community. The Action Replay hardware and it's software was cloned, localised and modified a lot throughout the years - here is the place to gather this specific historic information. This wiki serves the purpose of documenting differences, bugs and extensions, make them available at one place and take some pieces of the software to new grounds. Other multifunction cartridges will be covered here as well, but not as extensively and mainly to exploit feature ideas or to round the overall information.

The Targets: To-the-cycle exact reproduction of all digital parts including sound and envelope generation and paddle readouts; Exact modeling of the analog parts leading to a result that is almost indistinguishable from the original; Making it configurable to easily switch between various SID variants; Adding extra features like wavetables, stereo sound, more voices etc while keeping full compatibility.

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. We have used Tape Manager V1.3 to organize the content, so that it can easily be used with the NOVA64 front end which also has features to run the images on both emulators and real C64s.

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.)
