Quoted from WH20_Buzz:
Its not a Hack, at least its not now Buddy and I have no plans to sell them or manufacture. None of you could afford me!
I'm an Avionics Engineer by Trade.
Here is the latest fully unhacked version for those of you who can be bothered, nah just go back to your Netflix...lol
If you want to make it then all you need to do is order the Bits from Great Plains Electronics. Just buy the 24 Pin Connectors and cut them down to length.
Details are in the Wiring Diagram
Don't forget the Contacts AWG 20 to 18 are the ones you want. If you don't have heat shrink just use Hot Glue.
The Board I bought was less than $ 8 delivered to the Door...Takes forever though.
Here is a Vid showing how well it works and how good it looks...HA..HA

Looks like the 1237board works fine.

That said, it hurts me watching you switch the machine on and off so quickly. I can almost feel the power supply begging you to stop!

In case anyone is looking for the $8 UPC1237 board, with fast and free shipping, here you go on AMAZON!

OP
Quoted from marschner:

Actually I did try to use 12V DC from J115 (not regulated) but almost same result when turning off. Maybe a little bit better but not very much.
Should 18V AC be better?

ANY source of switched AC in the pinball machine will vanish instantly when the game is turned off. If you have an AC powered relay, it will open instantly to prevent the pop at power off.

If you search a bit, I think you can find an AC powered time delayed mechanical relay which will wait 1-2 seconds to turn ON after AC voltage is applied and then turn OFF instantly when power is removed. I know they exist because I bought one for Funhouse that I never installed.
