Just a follow-up -

I found the "pause" button!

It is about the size of a pinhead and black (just like the surrounding plastic). It is flat to the plastic & a little rough - I'm guessing that it was "adjusted" some time in the past, as it is now almost invisible and unusable.

Not a big deal really, since I am still trying to figure out a way make the 1 ball-per-shot a system default rather than an active option.

I really want to thank you guys for continually insisting that this button was there - I never would have found it with your pointers.

Thanks, again - and I hope to return the favor one day!
