I asked whether you can connect a SS1 type monitor to a sun 3/50, perhaps
with a converter of some sort.
There are certainly differing opinions on this. Responses are divided 50-50
between "this should work without problems", and "impossible - at least
without relatively expensive hardware".
Those who have actually tried something like this all belong to the
latter group, so I guess thats it. I enclose one response to represent the
correct answer below.

From: jxh@icdwest.ICD.Teradyne.COM (Jim Hickstein):
I went through this recently. No, you can't connect the DE-9 to the 13W3
because the electrical levels are not compatible. The DE-9 is ECL levels,
and the 13W3 is... well, not. I had tried to upgrade a 3/75 to a 4/40,
which entails keeping the monitor, but Sun had to ship me a special S-Bus
board with a DE-9 on it: the ECL monochrome frame buffer board. It's
usually $1000 (!) although it can also do hi-res (1600x1280?).
So, no, a cable won't do it. You may find some external box that converts
levels, but I doubt that it would be cheap, and it sounds like you need
it converted in the abnormal direction (3/50 to 13W3 monitor). Good luck.
