That would be HP's Visualize-EG (1280x1024, 8-bit) graphics card.

That an "EVC" (Enhanced Video Connector) which pre-dates DVI, IIRC.
I've only ever seen it on HP equipment but apparently it was a VESA
standard.  Many of the signals it contains actually have nothing to do
with video.

EVC-to-VGA cables can be found via Google.  Probably not to DVI or
anything newer, though.  You might be able to make your own adapter for
just the video signals.
