Hi everybody,
My message on Fri, Mar 5 1999 contained three different questions:
> I have a DEC 3000/300X workstation, that has a 21-inch Digital monitor
> (Model no: VRC21-HA). I wanted to see if I can attach this monitor to
> my PC. Are you aware of vendors out there that manufacture adaptors

<wesley_at_yelsew.com> mentioned that he is using a VRC21-HA attached to a
linux x86 PC, using a 15-pin D-shaped connector at one end, and BNC
connectors at the other (widely available in electronic stores).
<eddie_at_thruput.co.uk> mentioned that he is using a VRC21-HA on a
standard VGA card.
Older Digital monitors were fixed-frequency jobs that will work only on
one setting. Finding that setting may be a problem unless you've got the
technical specs for either the monitor or the system.
A couple of pages containing info on connecting fixed-frequency monitors
to a PC are:

For RGB monitors, with 3, 4, and 5 bnc connectors, go to:

My impression is that this monitor is a multi-sync monitor; I do not
have its technical specs though.
In conclusion, I am not exactly sure if a VRC21-HA would work great, if
attached to a modern PC. What if it is a PC that is running Windows, and
has a more advanced graphics card than a stanard VGA card? In other words,
I would really appreciate it if people would go over this summary and try
maybe clarifying these points, because I am afraid I might be giving the
list incomplete information.

The answer is yes. The only difference between these two systems is the CPU.
Swapping daughter cards should cause no problems.
