It's actually a bit embarrassing that I didn't read the Meade page
properly: a few more lines and I would have found the link I wanted
right there in the last paragraph. Once I got the program back on the
computer all was fine.

I was downloading 43Ea as I had been experiencing the worst
rubberbanding and alt/dec rocketing (only word to describe it, really)
with 43Ed. The gentlemen at Bintel in Sydney suggested using the earlier
one. I'm following the sequence in the Fine Tuning Tech Tips for
post-downloading, so I'll train it today and try it tonight. I have two
90s right now, so I'm comparing them to keep the better one and sell the
other.

Cheers,
Tom

Mike here: Anytime the AutoStar goes berserk, a CALIBRATE MOTOR and TRAIN DRIVES will usually solve it. If not, then a RESET, CALIBRATE MOTOR, and TRAIN DRIVES is in order. Reloading the ROM is a last resort but doesn't hurt; just remember to CALIBRATE MOTOR and TRAIN DRIVES following the load.

Great that all is working okay so far. Rubber banding can be a problem
associated with some versions of firmware, but also can be attributable
to poor training; make sure that you train on a non-moving terrestrial
object far distant and that you use very high power or a reticle
eyepiece. Usually good training will clear this up.

Keep up posted!
