As you can tell from the website design, I am a pinball addict. It began with playing in public places after school in Wuppertal during the 1970s. Later I bought a 1977 Williams Hot Tip which resided at my parents home in Soest until 2005 -- it has always been lots of work to keep it running. When I moved to Ulm, I acquired a 1993 Williams Twilight Zone, which I later passed on to my brother in Böblingen. After building a new home, I bought a 1994 Data East The Who's Tommy, a great machine with some tricky parts that regularly have to be repaired. Christmas 2005, my brother's gift was a 1981 Bally-Williams Jungle Lord from one of his friends. It is an ongoing restauration project with many broken plastics, damaged electronic and mechanical parts and a worn playfield.

I have been building electronic circuits since I was eight years old, dozens of them with 6502 microprocessors, inspired by a Commodore PET at school and Rockwell AIM-65 at home. So software accompanied the hardware. During university, I learned that chip design is obviously one of the most interesting applications of computer science. Somehow very close to the old dream of self-reproducing machines: modern computers could not be built without the help of computers! Apple ][ My language card, 1979 Rockwell AIM 65 My micro-65, 1982
