Peter is tired of being called "Mr. Chen", even so certain individuals insist on it. No, he's not chinese.
Peter has seen lots of boxes you youngsters wouldn't even accept as calculators. He is proud of having visited the insides of a 16 Bit Machine.
In his spare time he ponders new ways of turning groceries into biohazards, or tries to coax South American officials to add some stamps to his passport.
Beyond these trivialities Peter works for
Klippel[
^], a small german company that wants to make mankind happier by selling them novel loudspeaker measurement equipment.
Where are you from?[^]
