The British flag This site contains all kind of information about hardware and software related to the older Commodore computers like the KIM, PET, CBM, VIC-20, C64 and C128. In 2011 I started to take interest in Commodore PCs and IBM PC-XT (compatibles) as well.
The information is only available in English.

Latest activities:
- Clearing up my room because I had no room for projects or whatever I wanted to do. But that meant I had to make some hard choices. One of them was selling/giving away all my Amigas and everything related with it. Why? I asked my self two simple questions: 1) Which computer (type) do I use the least? 2) Of what computer (type) do I have the least knowledge? In both cases Amiga was in the top three of the list.
I would have loved to be able to do more with the Amigas but as always: lack of time. I have been thinking about keeping at least one machine but looking at what was still left at the end and thinking things over again, I decided to stick to my first decision.
- I wanted to repair some VIC-20 and C64 boards that, after replacing the most common trouble shooters, still didn't work. I looked for diagnostic kits and decided to build them myself. Running the ROM for the VIC-20 on one of my boards I found out that it contained a bug: it appeared dead in this case while my own program found out that the video and sound part of the 6561 was bad. So I decided to write my own diagnostic routines. I also decide to connect some LEDs to the userport. The idea: display a code using the LEDs. If that isn't possible, and no sound and no video, The VIC-20 is really dead. I decided to use the same idea for the C64.
Once things are ready, I'll let you know.
