Sorry. I meant Sun monochrome monitors in general but wrote "ECL".
The ECL monitors have a DE9 input, the analog (actually gray scale)
monitors have 13W3. The gray input is on the green channel. Sync pins
etc. are the same as on the 13W3 color monitors. Therefore you can
connect them to a color frame buffer to get a gear scale monitor. You
can connect a color monitor to a BW2 with 13W3 output, but you will get
a green on black display. The BW2 doesn't feed red and blue.

I had one of those too. It was a fixed frequency monitor. Don't expect
this thing to work on anything but a Sun frame buffer with the exact
matching timing.
