SBM was maybe the first "fast" Bally.

There is a ROM image that does not score you a letter each time you make the loop from Seymour Shadow. This makes a good game into a great game.

You would be an idiot to pass that game up for $400......around here they are $1000 with a terrible playfield.

Also, make sure you perform the Bally service procedure to the opening of the Loop.

I've got 2 SBMs that never had it done!

Bally had a kit to update the horseshoe loop.

Here is a scan of the bulletin:

Post some pics with the glass off.
