Allrighty, the Alltek ultimate mainboard arrived 30mins ago from Pinball Spares (awesome service Mark!) and here is the update.
I doublechecked voltages before plugging installing it.
Set the game dip switches to Fathom.
Replicated the game settings from the old board onto the new (just copying some other dip switch setting).
Connected the connectors.
Fired up the machine, and...
Works perfectly! It boots, but most importantly it fixed all of those unpredictable coil firings and weaknesses!
Plus, I now have free play and, I could swear that the bumpers and slingshots are much more responsive now. Not more powerful but definitely faster to fire than they have ever been. So the machine just feels more lively. I also had some flickering in the score displays that has cleared up too.
I am one very happy customer. Best $250 I've spent on the pin so far.
Thanks for all your help and encouragement guys.
Matt.
