Home page

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. Later other interests were added to the ones I already had.
The information is only available in English.

The Dutch flag Deze site verstrekt U allerlei informatie over zowel hardware als software van de diverse Commodore computers: KIM, PET, CBM, VIC-20, C64, C128 en anderen. In de tijd ben ik mij ook gaan intresseren voor de Commodore PCs en IBM PC-XT (compatibles). Later zijn er andere interesses bijgekomen.
Deze site is voor de rest alleen in het Engels.

The renovations are finished and I can start up my own projects again. And I was able to add two more "projects":
- The Aster CT-80, a Dutch clone of the Tandy TRS-80 model I. I owned one and was given a second one. In fact it was the "School Euro rack model" shown on this site. I used to have one around 1990 but that one broke down. What intrigues me is that it is built on Euro cards. My goal is to document it as much as possible and to recreate it.
- I owned an Ericsson Portable PC and I was able to lay my hand on two more. Weird PC compatible machine. It has only 512 KB of RAM, not expandble on the board, and the one I took apart has a 512 KB RAM disk on board. It has a 8088 as CPU but in this case I de-soldered it and replaced it with a NEC V20.
Funny detail: I had little interest in this machine because having only one floppy disk drive and no way to expand it is not pushing my interest. But one of the two new machines was missing a cover on the left side. On the above picture you can see that cover sticking out a little bit. On my machine it was closed completely and as so didn't look as a cover at all. Most important: under that cover was a 64-pin DIN AB expansion port. 62 of those pins seem to be a compatible ISA slot. This means I (possibly) can add more memory and a XTIDE interface plus CF card. And that is the way of tinkering I like!
