Anyway, here is the YouTube Video of my four skulls working together:

Dang!! I missed this message. Excellent! Do you have any problem with overheating board or lines? That looks better than anything I've seen!

Dr M, I found a reducing coupler for my skull to a bucky body. I Found a 5/16" to 1/4", at McMaster-Carr, item #97088A190.

AWSOME BB!!! That's exactly what I need! Thank you

EvilBob....I haven't had any trouble so far, but I haven't boxed up the controller yet. Does it really heat up that much?

I wouldn't think so. There are no components on the board with heat sinks, which leads me to believe that nothing gets very hot. The board is only sending small pulses to the control wire of the servos. I would think that any heat would be in the servos themselves. not on the board.

What components on the board would be likely to produce heat?

I dunno. I never fired up 20 servos like you have all at once. I'm glad there isn't a heat issue! BTW, my wife just saw your vid and she agrees it's fantastic!

Excellent job HalloBob, I've got to add some back up singers to my bucky for next year. Has anyone got any first hand experience on how far an extension you can run from your PSC to your servos. I'm wanting to go about 25 feet but have not tried it yet.

I've heard people say that they have run extensions up to 75 feet with some good gage wire. I'm sure 25 feet won't be a problem.

I was thinking about cat 6 with 22ga. or if that won't be big enough, I use 18/7 for my pneumatics.

Being somewhat computer challenged, I need some suggestions on hooking up a Kit74 that just came today. My computer only has one DB25 parallel port and one DB15. I don't want to keep unhooking my printer every time I want to use the DB25 connection. I thought I saw a thread about adding parallel ports but I'm not sure what that would involve. Is this the easiest/cheapest way to go or is there another way??

You can add extra parallel ports to your computer. You can buy PCI cards that add the port like this one:

I saw someone on this board that added 3 to their computer.

joesmo - the 22 ga wire should be fine for runs of 20 - 25 feet. for longer runs, you probably want to go with your 18/7, but I would try the cat5 first and see if youy have any trouble.
