I am an electronic engineer, (of Dutch descend) specialized in designing PCB's for Analog, Digital and to a lesser degree RF systems. In the past I have designed (among many other things) Computers and computer subsystems, modems and audio recording equipment, satellite subsystems and cryogenic electronics. I am fond of retro computing, and own a collection of retro computers, and literature about retro computing.


my first computer was a nameless home-brew system based on a 6502, but never got finished because I bought a KIM-1 and later a LMW-80.

I worked for a small hobby computer company, and among many other things sold Apple ]['s, ABC80's and Olivetti M80 systems, but also many kits. Like the Junior Computer (a KIM-1 clone), the Acorn Atom and also ZX80 kits. Many of them I assembled for customers who wanted them assembled. For owners of ZX80's I would buit in ZX81 ROM's. I also built 48K RAM and our own Floppy disc controller and Centronics printer interface into TRS-80 base systems, which was much cheaper than buying an expansion interface. Later I designed and sold my own Z80 computer, a much improved Tandy TRS-80 model 1 clone that also ran CP/M perfectly.


I have been collecting old home computers since forever (actually the start was the three versions of the Aster CT-80 I ended up with after Aster went bankrupt), and I got many from the about ten years I worked for a charity thrift store. but even before that I had many systems. I was always on the lookout for a safe place to give them to for eternity. As in April 2, 2015 (on good friday) I have all my stuff away to "awesomeretro" ( http://awesomeretro.nl).

here is a list of what I donated on permanent loan:
