13W3's were used with Sun, SGI monitors.  I think NeXT may have used 
those connectors, or something very similar to those.

http://pinouts.ru/cgi-bin/view_filt.cgi?text=3W3&lang=eng says that IBM 
PowerPC machines also used this.

If I remember right, the 13W3 monitors weren't interchangeable, and if 
you used a converter, you needed to make sure that your monitor would 
sync up to the computer.
Sun for example was notorious for using fixed-sync monitors that 
wouldn't work with anything but their machines.

What's funny is that they usually OEM'ed their monitors from, say Nokia, 
or Sony, and you could see another non-Sun branded monitor from the 
other two vendors which would be multisync and would work with almost 
everything, but the Sun branded ones wouldn't.  :-)

I'm glad that era is over.
