Dear Wikipedia-User,
I am using Wikipedia since the first days, but I am not writing articles very often. If possible I am modifying existing articles based on my knowledge. Most of my wotk is done within the german wikipedia.
I have some knowledge in:
- Softwaredesign (more than 35 years)
- old and new computer systems
- HP-computer systeme from the 70ies up to the 90ies
- HP-calculators
- building interpreters and compilers
- realtime programming and QNX
- material science
