Quoted from ignat:I also noticed some strange behavior with Doctor Who.
I have 2 Doctor Who machines, one with original Williams MPU, one with Homepin
During Video Mode when you collect the extra ball the Knocker will fire when you collect the extra ball on the homepin and not with the original board..
Go figure.
Are both machines running the same rom version?
Maybe swap the rom chips between machines, and see if one rom fires the coil and the other doesn’t …
Be interesting to see!

Quoted from ignat:Yeah same rom chips from what I can tell! I don't really want to swap them, I just had the Bally/Williams MPU out to repair a faulty diode!
Fair enough too. 
The DMD should show the version number on the screen when you fire up the pin. Evidently two factory versions, L1 and L2. And maybe other versions floating around out there too.

Quoted from ignat:They both boot up with L2
Cool! Weird they are different.
Enjoy your bonus knocker sound.

Quoted from ignat:Do you have a Doctor Who rotordave ? Does it have the knock during Video mode?
It also does it during W-H-O Extra Ball
Its actually quite distracting during Video mode so I doubt its normal
I have the extra balls turned off on all my pins, so unfortunately I couldn’t tell you …
I’m sure someone can tell us …

Quoted from Tuukka:Are the country code DIP switch settings identical? Some countries have the knocker disabled because electromechanical coin counter is connected instead of knocker. Set "coin meter units" in pricing adjustments to OFF.
Nice tips!
