I have a decstation that used to show activity when I would turn it on.
Now, all I see is the following blinking light pattern on the back:

legend:X=off, O=on

XOOO OOOX then
XOOO OOXO with the last two leds alternating. After some digging through
the decstation manager archive I discovered someone else with the same
problem who found that his hardware manual diagnosed this as a system
board problem.

Is this box totally hosed?
Is there any inexpensive way to fix it?
If it is fixable, does anyone have any manuals/docs out there they are
looking to get rid off?

Thanks in advance for any help.
