Hmm thats all fine and good, unfortunatly the 2100 does not have a backup
battery, it only has backup resister. I may very well need a full brain
wipe ut I have no pc serial cable to use to connect to this stupid winblows
laptop, and I'm trying to get Basalisik working, but I'm not 100% sure that
it will work, and wiping my newt with no backup desn't appeal to me. In
regards to this anyone in europe have a pc serial cable I can buy/borrow if
your in the Paris area. The calabration doesn't seem to drift either, it
just is out every time I wake up the newt. Unfortunatly your training trick
doesn't seem to work with the newt either. Thanks for your help though,
there are defiantivly some good suggestions in there.

I had this daft problem on an old 130 that I dug out again after a couple of
years. The calibration was so far out to the left-hand side of the pen that
I couldn't acknowledge the check-box on the 'communications card inserted'
start-up slip (this is without any backdrop applications). Like you say, a
reset did the trick but it had to be the full brain-wipe. Soon after that
the backup battery reported itself as duff, so I changed it and after that
the problem ALMOST disappeared. However when I switch it on now after a day
or so the pen has drifted about 2mm off, again to the left. I would say
first try cleaning the backup cell contacts or just changing the cell to see
if that helps - even though you can be on full adapter power, remember Apple
has a proud and solid history in its ability to build in a plethora of
unimaginable consequences of a bad PRAM battery.

Strangely enough I found you can train the line to join up with the pen
again by switching to line ink and moving it in a sort of square spiral,
clockwise, making sure you go to the edge of the screen left and right.
Each time you get to the right-hand side the line is a little closer to the
pen, until after about three circles later when it matches. It seems to be
stable like this until you turn the thing off. I only post this last bit as
another observation of a possible self-adjustment mechanism, and not a
solution - perhaps a proper re-alignment with the three X's is quicker.

Buggered if I know what's going on though.
