So I keep wanting to take the plunge and make a megaman table... I think Elektra could be a good jumping off point, with the basement PF being the "boss room". I would want to re-rule using a P-ROC but would one be compatible with Elektra?, in particular which one would be compatible with Elektra?

P-roc isn't compatible with early Bally solid state games.

The P-ROC boards were designed as a drop-in replacement for later WPC, WPC-95, Stern Whitestar, and Stern SAM boardsets. Not classic Bally/Stern systems.

You might be able to adapt the playfield harness. However, the 6-digit displays probably wouldn't work without some sort of custom logic adapter board.

There are a few system 11 machines that have been adapted to work with P-ROC:

If you really wanted to, you could gut the machine, leaving only the playfield assemblies behind, then wire everything up and use an alphanumeric or DMD display. This won't be anywhere near plug-and-play.

Honestly, though, if your Elektra is a half-way decent machine, I would leave it alone. Personally, I hate seeing machines destroyed if they can other wise be saved. Another option might be to sell the Elektra to fund building a custom machine. $500-$900 can get you well on your way with some boards, a blank playfield, and some basic playfield parts.

Here's a big thread that many hobbyists were contributing to: https://pinside.com/pinball/forum/topic/lets-figure-out-the-bare-minimum-costparts-to-build-a-whitewood

Surely there's a way, ask over on http://www.pinballcontrollers.com/forum/index.php

just use P3-ROC, gut the machine and add lamp, switch & solenoid boards.

Quoted from epotech:

P3-ROC can only use an LCD as display output and uses direct switches, rather than a matrix. In that situation, you would likely have to scrap the wiring harness.

If you were starting from scratch, the P3-ROC has some benefits over the P-ROC since it was designed just for that purpose.

It would take a fair amount of custom circuits to interface to a P-Roc.. but hell, it's been done with a sys11.. so I say totally doable.

Don't wreck an Elektra, I love it

If you are gonna strip the Elektra, I'm interested in the upper right hand corner plastic and triangle shaped piece in the middle of upper playfield!!

I'm wanting to do something similar with a likely unsupported machine (exact machine is yet to be determined). My current feeling is that I would have no desire to use the machine's existing switch matrix, harness, or boards. For the sake of having complete understanding & control over what I'm building, i'd love to re-wire every switch and lamp for direct input. If my understanding is correct, the P3-ROC is what I want for that, then?

With the theme I have in mind, I'm hoping to use RGB LEDs for as many playfield and even GI lights as possible. Their direct input PD-LED board claims to only support component style LEDs though, not the standard pinball style bulb. Am I understanding correctly then that I'd have to use the 8x8 matrix boards for all lighting if I want to use standard pinball bulbs? I suspect it would be far cheaper & simpler to use direct component style LEDs, but what would you say are the pros/cons of that approach?

For anyone pondering the display issue, there's a thread on the Multimorphic forums about redoing a Flash using the P-ROC. The individual there also linked to their post on Pinside about the segment display driver they built using an Arduino Uno:
