-------Commodore Trivia Edition #34 Questions and Answers Preface--------
Not to leave you in the dark for too long, here are the trivia
answers to the previous edition of Commodore Trivia. I am posting the
answers at this time, and will post the scores and winners in a few
days. This time frame is set up to allow time for any discussions on the
correctness of these answers. By this time, the newest edition of
trivia has been posted. I encourage you to enter it.
This edition of trivia answers has been posted to the USENET newsgroups:
comp.sys.cbm, alt.folklore.computers, and comp.sys.amiga.advocacy. It
has also been posted to the FidoNET CBM Echo.
Feel free to use these trivia answers in newsletters, magazines, and other
publications (please see disclaimer). If you use the trivia, I would
appreciate knowing where it has ended up. If you intend to use this
information, please wait a few days after the posting date to allow for
major errors to be corrected.
