Konami PCB to Jamma Adapter for Time Pilot

[bfrosty]

Hey Guys!

I noticed a member over at KLOV that kept his original Time Pilot PCB, but added a 60-in-1 in addition.

I would like to do this, since my Time Pilot is a mutt, not a true TimePilot.

So...
1) Buy the Konami PCB to Jamma adapter.
2) Buy the 60-1 Icade PCB.
3) Connect the Time Pilot harness to the Konami PCB Adapter on one side and the 60-1 on the other?

I did notice the Konami board has a jumper to use either -5vdc or not.  How do you know if you need to use -5vdc?  My power supply uses -5vdc.

Any advice or am I missing any other boards or wires/harnesses?

Seems pretty simple.
Thanks,
MK
