How are your soldering skills though. There are some VGA-->BNC cables on ebay, I got one last week for 6. You could cut the vga connector off and solder to a 3w3 plug. You should be able to get one through RS or Farnell cheaply
The issue is thus: I(t's a DEC cable with a moulded 3w3 plug and the cable has pulled at the 3w3 end, I suspect the wire has snapped inside the 3w3 plug. I'm getting another cable to prove the VAX is okay first and when I have that working I'll do some surgery on my existing one.
I'de make one up using existing stuff I have if I had any idea where to get 3w3 plugs from, they seem to be like rocking horse doo-doo.

Hi,
I wondered if anyone has a spare 3w3 to 3xBNC (RGB) cable. It appears after a multimeter test that the green wire in mine has broken, the cable insulation has split behind the 3w3 connector so I think the cable has been pulled on and broken.
Make that two. I'm also on the hunt for one. :-)

Thanks,
Mark - there is currently one on eBay unless it's been snapped up.
I can see 3 - all in the USA.

Thankfully, we'd /probably/ be using something a wee bit faster than a 64K
leased line. ;)
As far as I recall, DEC originally required that a network interconnect cluster
required 10MB/s connections. I think they also said that all the nodes had to
be on the same ethernet segment with no repeaters or bridges intervening! Maybe
that was just a way of being able to blame the networking equipment if there
were clustering problems when the customers invariably ignored the rules...
I suspect usable clustering would probably need a couple of MB/s of stable, low
latency networking between the cluster nodes in both directions. In most
realistic cases, something would be needed at each end to encapsulate the
cluster traffic for transport over IP.
Clustering over slow or unreliable links is not pretty or fun. The results are
generally poor performance, with hangs, timeouts and machines falling over,
with all cluster nodes affected, not just the ones on the wrong side of the
link. VMS does clusterwide locking on almost all shared resources. If a node
can't reliably make contact with other nodes in the cluster, things start to
fall apart very quickly. Unlike DECnet, clustering is not designed to gracefully
cope with network problems.
