Commodore 1541 floppydrive ieee488-interface
TMO Jan 05,2020
The ieee488 interface is compatible with the Commodore floppy drive 1541 (version with built-in power supply).The interface changes the serial bus into a parallel ieee488 bus. The Commodore floppy drive 1541 becomes comparable to the Commodore floppy drive 2031. The serial bus no longer works after the conversion. Reading and writing on diskettes is up to 6 times faster.In addition, an ieee488 ROM is required for the floppy drive 1541 as a replacement for the original ROM 901229-03 on UB4.

Commodore 64 PLA replacement
Mantione Dec 31,2019
This project is about a Commodore PLA replacement.PLA replacements for the Commodore 64 are available for quite a number of years and have grown increasingly sophisticated. Therefore you may ask why the world would need another PLA, and indeed, current available alternatives are technically sound. However, if you occasionally repair a Commodore 64, you will come to the realisation that you need spare PLAs on stock. Now I'm not saying people that make PLAs are overcharging, in fact, I believe for...

Commodore 64 Modulator (revision C)
Lunde Nov 09,2019
The latest thing is appearantly replacing the modulator on the Commodore 64 boards in order to get rid of some of the mess found in the video circuit, the idea is that less components is less components to add noise to all of it (you can also omit components for composite video as well if only S-video is to be used with the computer). I found the schematics for a version of it created by Zero-X/OMS, this has been adapted to a physical PCB that should fit into the spot where the normal modulator...

Commodore 64 Stereo SID (revision C)
Lunde Oct 19,2019
There are many Stereo SID boards out there, but this one is mine - mostly because I did not feel like tracking down or paying premium to get one of those wirewrap sockets. Using a simple board like this will put a second SID chip at $DE00 and add 3 voices to your system, with suitable software and a selection of SID files you can play music on your system like never experienced before (your mileage may vary)! For everyday use you can use it in pseudo stereo-mode by having each SID play the same ...

Commodore 64 Lumafix (revision B)
Lunde Oct 19,2019
There are a few versions of the Lumafix board available and this is mine,a simplified version that should be easier to solder together for beginners with access to a modest selection of functional set of soldering tools. Gone are the slightly confusing surface mount options that's mostly only suitable for those with more advanced skills, so what you need to add is what you see!For those not familiar with the Lumafix board, it is a circuit designed to attempt to minimize the amount of vertical ba...
