I've had the hardest time finding a Scramble Harness.. I've been told too just wire it Jamma but would it still be a completely restored game?

Does the Harness have anything too do with the Monitor Wiring? Would'nt i need a New Switching PS For this allso?

How would i go about wiring the scramble cp?

these are just questions before i need up making the order and doing everything.
 
If you go to crazykong.com and check the pinouts of the Scramble and Lost Tomb harnesses they are very close. I could be wrong, but it looks like repinning a few connections at the pcb connector and probably some at the control panel and you would be in business. -Barry
 
This is what I use:

To do this:

I probably have the parts to and would be willing to help...
 
If you have a complete Lost Tomb harness, you only need to repin and possibly replace the CP molex (that's if you have a dedicated Scramble CP, with wiring.) Scramble will come up and even partially play with your existing LT harness. Is your Lost Tomb still together and working? That's how I tested the last Scramble, Time Pilot and Tutankham PCB's I sold. The Stern pinout is virtually the same, it's the control mapping that's different.
 
Looking at the pinouts it appears that just controls are different...

Power/video is the same and should just work...
 
scramble pinout

yes the game works fine in the cab thats not the problem ! The controls are messed up the rocket does'nt move down.

The Connecttor does'nt fit for the Scramble control Panel into the Lost Tomb Harness.
 
what do you mean, "The connector doesn't fit"? Which connector, the CP one or the edge?

I'd just replace the CP connector and re-pin it to match the scramble CP. If you still have the lost tomb CP, it might be worth making an adapter to go from the lost tomb CP connectors to the scramble CP, so you can swap CPs back an forth and play both games.
 
My thoughts exactly Mark.

I can either help you re-wire the CP connector or help you build an adapter...

Yes i would rather have a adapter made then Repin it. Since i still have everything for the Lost Tomb so i can play that allso.

Shill i sent a Pm i have'nt heard from you yet!
