Nick,
You've lost the "tick" line into one of the 8520's…or you've lost
the 8520 itself (most likely occurance). The 8520 would be labeled U300,
I suspect you may also find you have problems with your parallel port
and/or your internal floppy.
The tick line is supplied by one of two places…by default, it
comes from the power supply, but by changing jumper J300, that signal can
be obtained from the vertical frame rate.
Have your dealer's tech take a look at it, unless you know what
you're doing…I wouldn't suggest you attempt swapping the 8520 yourself.
They are VERY sensitive to static.
Don
