Hi!
I'm working on these mobos, I mean,  I'm traying to repair Alpha 255 motherboards. Do you have some information or know sth about this mother?
When I turn it on, there's a green led that doesnt turn off. So, the problem could be linked with components that make the start of the mother.
Do you know sb to contact and talk about this?

I'll appreciate your help! Thanks a lot!

Hi,

Post some pictures showing the issue that you have and maybe someone here will be able to point you in the right direction.

A common fault that these boards do have is the failure of a tantalum capacitor in the PS/2 keyboard circuit. In the case of my board, the cap was factory placed with the wrong polarity. (Later revisions of the board had the cap placed the other way around, so when I replaced it I orientated it in that way.
