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 gave all my gaming stuff away to "awesomeretro" ( http://awesomeretro.nl). disappointingly they never wrote about my large donation on their site, but if you look at this picture, (made shortly afterwards) you can see some of the stuff I donated on the table through the door opening: http://awesomespace.nl/wp-content/uploads/sites/14/2015/04/awesomespace-tactical-unit.jpg

I still had about 80 "non gaming" systems, such as my Aster CT-80 collection, and many others such as an Apple 3 with hard-disk, for which awesome space had no interest. These went to the Bonami Computer Museum in Zwolle. I still have a few PET computers at home, with a dual floppy unit and a P2000, all of which I repaired, or will repair in the future.
