        As a spinoff on the recent discussion about the jumper setting of
J300 for video purposes, I was wondering if anyone (possibly Dave) could
assemble and post (or mail me) a list of what all the jumpers in the B2000
are.  I have REV 4.2 so I am obviously interested in that but no numbers
should have changed throughout the B2000 line I don't think.

        Also, I recently downloaded a program called 'Calibrate' which
allows you to calibrate your battery backed up clock.  It prints out the
error between the battery clock and the normal system clock (run by the
TICK line I would assume).  It mentions an adjustment pot on the clock that
you may turn to adjust it's speed.  Where is the clock circuit?  I'd like
to know for two reasons - this adjustment and for when I may need to
replace the battery.  I saw a yellow coloured trim pot at the very front of
the case in line with the Co-Processor slot, is this is?

        Also, again, Which chip is Kickstart.  I'm still running 1.2 while
waiting for 2.04 (or whatever) to be burned and I haven't had to touch it. 
It is not labelled on my motherboard.  I think that it might be the
socketed chip at the mid-rear of the motherboard.  Am I correct?

        Thanks in advance for answers to these questions...
