I found some pictures of what it might look like with both board sets installed.

What a nice machine... My problem is I can't find any tech info to bring this mod to my own pp cab.

I have searched and searched google and here on klov. So how do I install both pp1 and 2. Anyone have any links to instructions or maybe some more pictures?
 
i looked through the pics - he just turned the cages around so the open end faces forward and then opens the coin door and swaps connectors from one to the other - or that's how it looks.
Once upon a time i had both PP 1 and 2 in one cab, using a parallel port switch to switch between, along with a few other games. I've since moved the PP2 back into the PP2 cab. The shoort answer of how i did it was this - I made an adapter that plugs into the original wiring. From there i split the power wires onto a bus, then switched the ground for each boardset. All the control wires were routed through the parallel port. So, to switch games, you just set the ground switch to the board you want, and the same with the parallel port switch.
 
Thanks for that post man... That's exactly what he did. All you need to do is reach thru the coin door.

I wonder how the switcher mod will be affected by adding two boards? The Startech doc doesn't cover that...
 
doesn't effect the mod at all. You can see the 2 molex connectors he's tied on each pcbset - those are most likely the power connectors.
