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 an 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 my own Z80 computer, a Tandy TRS-80 clone that also ran CP/M perfectly.
