Another question- so far I have had two Sun-3 era machines (a Carrera CPU in a CADDstation and a Sun 3/200 CPU) develop "all lights on" catatonia. Is this a common problem with Sun-3s? I'm wondering if I should take the time to trace out the 3/200 board (preferably with hints on where to look), give it away, or junk it (I have a working 3/110 system, so I won't be destitute of Sun-3s).
