Hello and welcome to my homepage.
I am an electronic engineer, and ever since the 1970s I have been busy with microprocessors, designing micropocessor based electronic equipment. In fact, in 1980 or so, I designed one of the first Dutch Microcomputers, called the ASTER CT-80. It was a TRS-80 clone, that could also run CP/M. Since then I have been interested in the history of computers. I own an extensive library with German, Dutch, British and American computer magazines. For example an (almost) complete complete collection of BYTE magazine. I also collect old homecomputers of which I have between 80 and 90 (I lost count), with my oldest computer being a Datapoint 2200, which is considered the oldest system that can be considered a Personal Computer, and which CPU architecture has Insipred the architecture of Intels first 8-bit CPU. A CPU architecture that is still used in the CPU's of all PC's (and now Mac's too).

[edit] Some of the articles I created
- Home computer remakes and its category page [1]
- Exalt (software)
- Experiment-s
- Linpus Linux
- Electronics today international (magazine)
- Elektor Junior Computer
- GOS (operating system)
- Influence of the IBM-PC on the PC market first started as mainly a list in Personal computers, later became an article about this topic.
- Nuna4 and Twente One Dutch Solar cars in 2007.
- List of MSX compatible computers and an example the NMS-8250.
- List of MSX emulators.
- List of Apple II clones and List of TRS-80 clones
- Xbox 360 disk scratching problems Investigated and massively expanded this part of the article about Xbox 360 hardware problems.
- MSX-DOS about the disk operating system for MSX standard home computers.
- List of microprocessor development boards about systems such as the KIM-1 and motorola MEK6800D2
- Panasonic JR-200, a rare home computer, one of a very few systems to use a 6802 processor.
- I wrote an article about "Watara Supervision internals" and a similar article "Mega Duck internals" so you can see the similarity of both designs. These pages have since been removed from wikipedia main because they were deemed to be "not encyclopedic", but the pictures I took for these articles can still be found here.
- 1chipMSX about the return of MSX home computers. Programming FPGA's in VHDL anyone?
- Mega Duck/Cougar Boy Just two rare Handheld game consoles I have recently acquired. I now also took a picture of them, and placed it in the article.
- Parallax Propeller, The most interesting Micro-controller I have seen in a long time (upgraded from the stub).
- List of home computers by video hardware What have I gotten me into, this is promising to become a mayor job (I love to do).
- Video Display Controller is a subject that's near to my heart, it indirectly directly lead to start the List of home computers by video hardware.....
- Comx-35 Still don't have found one for my collection, (I own about 80, I lost count, home computers and game systems) but I remember these.
- Kilobaud Microcomputing (magazine)'s are part of my extensive collection of home computer magazines. I liked them because of all the Schematics in them.
- Electronics today international (magazine) is another very old magazine that very early published designs of Home brew computers. I remember the "system 68", it did not have a keyboard or any other input device, you could only use a lightpen to turn on pixels (memory bits) on and off, and to start your program. That is in the time that everybody else used a switch-panel and led's, like the Altair. A very odd system! Maybe Ill write an article about it someday.
- So, I like obscure old home computers, the PSI Comp 80 (computer) is certainly one.
- The DAI Personal Computer was another one, from our friendly neighbour country. It died an un-deserved early death, but had great potential.
- Talkie tapes a funny way to store audio.
- List of edible fish and Barnevelder are from the time that I was organizing categories of foodstuff.
- Logic family is about the different kind of digital logic families, like TTL logic, the current article still resembles my starter.
- Visual thinking I wrote shortly after I discovered I am a "picture-thinker" myself, I think I did not even have a user page here.
I did much more, and older stuff, (the oldest may well be the article about my Aster CT-80) but I have to stop somewhere with this list.
