OK, I'll take "Useless Hobie Trivia" for $1000, Alex.
I offer these for your list, in rough order of appearance. Others can fill in the blanks and pinpoint the years. If I missed anything, our jeopardy master KBob can chime in with it.
Beebrain, since you brought it up, we'll let you organize these braindumps by product and year. I just hope we are not duplicating the work done by MadMax.
Thanks.
