Thanks for the help!
Grasshopper:
Yes, if the Ipac VE doesn't have a +5v connector, you can take +5v from the USB connector.

LEDs only require a miniscule amount of power so there shouldn't be any problems. If there was an issue then USB keyboards wouldn't have LEDs.

Then I can wire everything up as shown on the Ultimarc page, right?:

Right, and the first screw terminal on each side nearest the keyboard port should be +5V, judging by the pic on the www.ultimarc.com website.

I have an I-PAC VE and have successfully hooked up LEDs to flash my player 1 and player 2 start buttons.  The input assignments are as follows:

Num lock = 2P-D
Caps lock = 1P-D
Scroll lock = 1P-A (I think, this one always lit the LED)

I didn't use the scroll lock LED for anything, so I use this for player 1's button #7 as you normally would.  I actually like these assignments, as the two LEDs I was interested in are hooked up to the D inputs.

I wanted to use superbright LEDs, so the +5 on the I-PAC didn't have enough juice.  I followed the guide here to drive them with an external 5 Volts taken from my computer's power supply:

You can use the same control board for the VE, just remember that the inputs are different.

I used superbrights because I was sticking these LEDs inside happs buttons.  I saw the idea here:

If you're using standard LEDs, then the +5 on the VE works fine.  I tested them to make sure.  If that accomplishes your goal, then it greatly simplifies the process!


And last but not least, make sure the "led_mode" setting in your mame.ini is set to "usb" instead of "ps/2" or it won't work.
