I would be interested in one of these shields. Could it be used on a System 11 board?

Quoted from Prof_Pinball:Yes -- this *should* work on a System 11 board. I checked out the circuit diagrams for Whirlwind. You'll only need to use one plug to tie into the flashers (not too many in that game) and their power. The power is 5J11-1, and the flashers are grounded on 5J1. The input voltage is rated higher on this game (+25V) than Sterns or WPC-95s, but the 10k resistors should cut it enough to not blow the opto-isolators. We don't have a system-11 to test this on, but if someone wants to lend us one, we can try it out.

I would like to test this in my BK2K (system 11), I want to add a shaker motor. There are more flashers in BK2K than Whirlwind, will that matter?
Edit: Another question, Will I be able to sense the power to the flippers so that it only watches the lights when a ball is in play and not when it's in attract mode?
