Hi guys I'm currently tuping on Lexmark 122 terminal board with blue cube adapter, bought a new black color Unicomp of ebay for descent price thats PS/2 and really want to be able to use it. But thing it is cant get it to work, I did not tried plugging it in PS/2 direct, should work with the blue cube anyways. Also I think the cable sort of got warmish after being plugged in for 20 minutes.
Any help would be appreciated, thanks.

Try a different computer, the usb on that particular motherboard might not have enough power.
OR, it could be that the 5v rail on your power supply is super weak. This is less likely

Cable getting warm doesn't sound good. And usually a sign of too much power flowing rather than too little! It could mean that the keyboard is fried.
Otherwise, at least some of these PS/2 122s from Unicomp have a jumper that can be removed to put them into a 'code set 3' mode, which would not be compatible with a blue cube. It's highly unlikely to have fallen off during transit though (and pretty unlikely to have been removed, I would imagine). On some it's JP3 (http://geekhack.org/index.php?topic=10985.60) and on others it's JP2 (http://geekhack.org/index.php?topic=17458.msg648235#msg648235).

so what you are saying warm cable means something wrong with the keyboard in first place or? BTW the mobo should be descent its ASUS ROG III and the power supply is Corsair 1000W

I'm not thinking it's your computer. If it was your computer, it would be doing the same thing with every keyboard you plugged into it, wouldn't it?
Now are you sure that you're blue cube adapter is functioning properly? If it was broken that could potentially be where the problem is.

Probably :(
The only time I've heard of a warm cable before is after Paranoid applied power backwards! It was confusing though, because it didn't seem to be drawing enough current to heat the cable up. See here (http://geekhack.org/index.php?topic=17458.msg619737#msg619737).
Of course, that isn't necessarily what's happened to yours! But it sounds similar. There's not a complete short, because that would cause the USB port to cut power (hopefully!), but logically it must be drawing excessive current to be able to heat a cable up.

yes the blue cube adapter works fine with every Model M including my current keyboard which is Lexmark terminal 122 Model M also, and the USB port its fine cause after I was done testing Unicomp I plugged back in the Lexmark and all is fine.

i have 14 days return policy, what would be your guess Soarer, more of an faulty keyboard and ask for replacement or should I get full refund. I have no problem to give it a shot with another one, the keyboard looks smexy lol

Not sure which I'd do... probably try a replacement, I think. And ask the seller to test it first!
