I don't even know if I want to admit this...

But as it turns out the problem was the PSU. One of them is a PS407, the other is a PS705. The 705 is rated at 70 something volts, and the drive only takes something like 48 if I remember correctly.

Anyone want to buy a PS705 unit? :D

Keith: Indeed I am back home, putting the finishing touches to the machine finally :). The phone was flat, again. You mind if I give you a call tonight? Need some advice on setting up mach if thats alright. Also, I'll need a nice thick table with t slots made up. If you interested in a little work.
