YES!  Finals are _OVER_.  Win, lose, live, die, pass, fail, another semester
(actually a pretty good one!) is over.  Now for the fun stuff...

I'm back to work on the temperature sensor project, and should have something
working before January 15.  I've not finished the (now ancient) 512k SIMM
upgrade project, simply because the prototypes I have built are not reliable
(the machine crashes after a few minutes).  I suspect that the de-glitching
cap I am using is too small, too big, or too slow.  It's tantalum, though,
so it shouldn't be too slow (unless it's _WAY_ to big.).  I haven't had
enough engineering classes to know.  Also, I may be getting some capacitance
on the address or data lines from my crappy soldering.  I'm gonna get a few
plated-through boards made and see if that will help.  I first suspected
that something was overheating, but everything stays cool, even after It
crashes, and nothing has been damaged.  All the signals look good on a scope
(at the pins where they are supposed to be.  Only thing is the scope loads
the line a bit and crashes the machine when I check some pins.  Maybe I need
a better scope?

26 days till I can order (the rest of) my Delmar Sys V!  I'm about to go nuts
here....

Everyone have a very merry Christmas, and I'll keep you all posted if I
actually get something done on the temperature sensor or SIMM Upgrade!
