I've thought about using the stealth shift option with the Ipac. The only problem I have is I'm not sure what ratings (voltage / amperage) the componets should be (diodes, caps) . I'm planning on ordering through newark, but before I did I wanted to make sure I got the right stuff.

Never heard of this...what is 'Stealth Shift'?
-
i think this is what he is talking about:

ooooo, i see it now, it pushs the shift button and origional button at the same time. Hmm...intresting
-
it's low voltage and current so any cap of that rating should do the trick. the diode is just to allow current to go one way so any small diode will do the trick too... same with resistor, 1/4 watt will be fine
-
The diode I was looking at was rated for 5v @ 50 ma, but I'm unsure if I should go higher. I'm a little gun shy in just throwing something together without knowing what the componet ratings should be. It really sucks to fry some componets because they were under rated.

For those unfamiliar with it, there's also information at http://www.mameworld.net/tigerheli/encoder/shiftkeys.htm
I don't know the component ratings required. I would think they would be minimal, but it wouldn't be a bad idea to contact Andy Warne at www.ultimarc.com and ask.
And I would like to emphasize that the following from my page still applies:
Remember that pressing a shifted button causes all the buttons to send their shifted inputs. Therefore, if you use this method, I recommend that all keys that will not have a specific shifted function be programmed to send the same value shifted and unshifted. And the less shifted inputs you have, the less problems you will have, but it is a very useful feature.
