IIRC, VRC21-xx are all multi-sync VGA monitors, most of which had
those BNC-style connectors. The cables with those were notorious for
going bad (I've replaced a dozen or more over the years), but they are
the only game in town for those monitors with only the BNC connectors.

Well, a normal VGA PC's monitor should have a plug to connect to the
VGA port on a graphics card; the Alpha graphics card should also have
one of these, as the cable from the Alpha to the VRC21 has the
BNC-style copnnectors only at the monitor end.
Good luck.
