Super bright LED driver board for I-PAC

We plan on producing schematics for making a qbert knocker. Actually, the schematics are already out there, but I suck at reading them. Kelsey agreed to make it for me if I do the mame hack for him:) Just a normal parallel port relay driver. USB drivers are EXPENSIVE, though we both would rather see that.
The schematic could can control 8 relays. Actually, if someone knew how to control do microcontroller programming you could control 256 relays since there is 8 data lines on the parallel port. (USB would be simular) Would involve alot of hacking mame, but some relay cool custom hardware could be made.
If someone has or wants mroe info PM me (not kelsy, he gets enough I am sure). As this was more my idea than his, he's just being nice and implementing the hardware for me:)

AIEEE!! :o How did you guys know I was working on this! :P Well, so much for 1UPControls... I was going to try marketing both of these products (LED board AND relay board) but you guys beat me to it!! Oh well...
I'm still interested in what you guys are doing. I'd like to get my T2 guns up and running again! ;D

Actually, it's been discusses a long time ago too.
I think I have the mame hack working, won't know until I can get some hardware to test:)
BTW, you still could market a relay board, but schematics are free on the internet anyways:)

Holy smokes! Do you realize that even though I currently own a KE72 that has not yet been used I am now seriously considering buying an Ipac so I can have the led feature?? Great work Kelsey! And thanks for encouraging me to spend more money!! ;D

The KE72 is supposed to have the LED feature built in.
I have a KE72-T that I purchased when it first came out and have now dusted off the box to use it. I had trouble programming it in XP and I contacted Hagstrom. I also asked them about the LED feature because I thought I heard here that it was an available upgrade years ago. They said it is built into the KE72 and they told me to send my KE72 in to them and they would test, verify and upgrade the programming for me to the latest revision. They also have a new version of the command line programming software that works in 2000/XP that they are sending me. I don't see any reason why you could not make an LED driver board using Oscar's approach on a KE72.
Sasquatch!:
Oscar, thanks for yet another fantastic contribution to this board! And for adding more work to my @#$% cabinet! ;)
MannyTC: Really - the KE72 supports LED? I was thinking the same thing as DZuroff, but now I might have to email Hagstrom and see about this. Thanks for the tip!
