Unfortunately, this is like saying "my modem doesn't work with my
computer" without giving more specifics.  Since the 3/80 didn't come with
an onboard framebuffer, it could be set up to drive anything from a 1-bit
ECL digital mono monitor to an analog color monitor.  Same with the Sparc
2.  You need to get the model numbers from the monitor and the framebuffer
from the 3/80 to figure out if it will work.

My guess is that the 3/80 has an analog color or mono framebuffer and
you're using an analog color monitor, but the sync frequencies are wrong.
The model numbers are the only way to tell.
