About Me


This is my personal website. I have gathered some information about my education and my private projects here.

In my youth I taught myself basic electronic skills. This knowledge was very helpful to me in my future career.
From 1976 to 1980 I studied technical computer science at the University of Applied Sciences in Würzburg. I learned programming on a computer from the University of Würzburg (a TR440 or Telefunken Rechner 440). At that time, the storage medium used for the programs was still punch cards. My first programming language was FORTRAN. Later followed Cobol, PL1, Algol, Basic, Forth, C and various assembly languages.
I did my first internship semester in a company that manufactured large newspaper printing machines. At that time there was an IBM 370 in the commercial IT department. In addition to magnetic tapes for long-term storage, punch cards were also used here.
My second internship semester was in an electronics laboratory at the ENT university clinic. Besides some microprocessor boards (6502, Z80) I worked with a Commodore PET. One of the first personal computers.
In 1980 I completed my studies as a technical computer scientist (Diplom-Informatiker / FH).
Since then I have worked for the following companies:

INCAA Computers, Netherlands, Apeldoorn, 2 years
In my time, INCAA manufactured, among other things, CAMAC bus boards, data concentrators and industrial systems based on the 6800 microprocessor.
I was responsible for the design and implementation of such system software as:

  • Real time multitasking operating systems
  • Enhancement of compilers and assemblers
  • Industrial application software
  • Data communication procedures
Connection of mainframes and peripherals was a focus of the company.

Dental Clinic of the University of Würzburg, Germany, 3 years
Here I worked in the special research area 92 (SFB 92). Biology of the oral cavity (Biologie der Mundhöhle).
In addition to supporting experiments, I was responsible for the computers. Among other things, we also built the necessary hardware.

  • Image processing, graphics, word processing program, Modua-2 compiler
  • Various interface cards for process control
  • Graphics system for displaying color images
  • Image processing computer with an Am 29116 microprocessor as CPU

Industrial image processing, Germany, Munic, 35 years

This company was specialized in image processing. Up to 20 people worked here.
In the beginning, all image processing hardware was built in-house. Later it was switched to VME bus system. Here, too, circuit boards for image processing were built in-house. When the PCs became more powerful and cheaper, they no longer manufactured their own boards.
Customers of the image processing system were primarily quality control in the manufacturing industry. Many of the applications had to do with the control of printing, hot stamping or surfaces.

  • Development and testing of image processing circuit boards.
  • Software for VME bus computer
    Real-time operating system, device driver, graphical user interface and for remote maintenance.
  • Software for Windows operating systems.
    Device drivers, graphical interfaces, scripting languages and much more. One focus was to optimize the real-time capability of Windows.
  • Management.
    In addition to the technical coordination with customers, I also managed projects, carried out material orders and instructed employees.
