Ruud's Commodore Site: My collection Home Email

My own computer and peripheral collection

I own quite some computers and peripherals, Commodores as well as non-Commodores. Once owning something, I also want to have the schematics and other related documentation of it. And I don't mind sharing this information with you.

If you miss some computers, like my KIM-1, I have sold them or given away. My main reason: I started as a collector but I in time found out that I more prefer to tinker with computers than to collect them. And the KIM-1 for example, is not a computer that you want to experiment with. Having a CBM 3032, why should I need two other computers with even less memory? So my 3008 and 3016 went to a Swiss museum, for free.

  • Junior
    This little baby is the 'brainchild' of Elektuur, a Dutch electronics magazine, also known as Elektor in some other countries. It has a hexadecimal keyboard + some extra keys, a hexadecimal display and it uses the 6502. "Just like the KIM" you probably think. I'm more then convinced that the developers of the Junior used the KIM as base; too much of the hardware and software looks the same. Any comments on this statement are welcome.

  • Micro-Professor (MultiTech)
    You can say this computer is the Z80-Version of the Junior. I started with building two myself. The first one started its life as an ASTER, a Dutch CP/M computer, but was given to someone who collected ASTER. The second one was based on the Z80 card developed by Elektuur.
    Two month after completing that one I bought a real one quite cheap because the seller made a typo in the advertisement on Ebay and I just happened to make the same mistake :) Later two others were given to me by Edzard Kolks.
