Emergency password deletion

Special thanks to Mel Patrick <mel@wabbitwanch.com>) for
finding a solution to erasing the code lock [page 64-65
"Pfaff Creative Instruction Book", if you do not remember
your Pfaff's password or Pfaff self locks.

SO....I unplugged the machine from the power cord, removed the foot 
control, and I once again removed the batteries. But this
time I left them out for at least 20 minutes.

There is some RAM in the machine that holds the P and M
memories plus some "preference" info like the codelock
sequence. There is a capacitor that stores some electricity
from the battery (or the power cord maybe), that enables you
to remove all power, change the batteries in a reasonable
amount of time and not lose any of the memory stuff.
However if you remove the power long enough, the capacitor
drains just like a battery and that resets the 
machine to null.

Now as to why this [phantom password] appeared, perhaps
that it's because:
1. we removed the power cord for so long
2. the batteries were low (although this doesn't make much
sense when 
I measured them)
3. the machine had a battery "burp"...;-)
