Yea you would think the -21 would work on anything like the Sun 20E20. I
have used a 13W3/HD15 adapter to run PeeCee's, HP workstations and all other
manner of machines on the Sun tube. Never had a machine that didn't work
with it. So, I figgured the SGI -21 was the same deal. <buzzer sound> Wrong!
I could get the SGI to work with anything with an HD 15 plug fine. But could
not get it to wok with a Sun no matter what I tried. I even got a 13W3 to HD
15 adaptor to connect to the 15 pin input on the SGI. No dice. Now there is
a hack to get the SGI 20D11 to work with Sun. It invovles installation of a
10K ohm resistor into the PCB that holds the 13W3 socket by all accounts it
works fine. SO I am thinking that maybe the SGI 21 is brain dead in the same
respect.

Sigh!
