Re: Star Wars auto centering?

Altan,

Yes, I remember your write up; I need to do this to mine, as mine has an
early version of the Clay Cowgill ESB/SW multigame that exhibits NVRAM issue
when switching between games and between power cycles. Thanks for the
reference link!

Initially my Star Wars needed to be calibrated each power cycle. However,
I ultimately correlated it to having problematic NVRAM writes. Once I got
my NVRAM working correctly, such as successfully writing using the stored
energy in caps when the machine transitions of power on to power off, I no
longer need to recal each power cycle.

Maybe I'm lucky --- I've certainly heard many people say it's normal to
require recalibration on power cycles -- but I don't anymore.

Do you have a stock SW or one with a kit?

Some info about my SW exercise is on my website @ www.aaarpinball.com
