This cable works just as you describe on my Sparcstation 2 with
an old moitor. I can report the monitor spec. if you need it.
I have no complaint with the price or function of the cable.
Thanks! I will make a note of it (busy chasing some other issues
at the present time).
I'm a week late responding to this but be careful: they may well
not work on any given monitor. The older Suns present a composite
sync-on-green signal as opposed to separate H/V sync on dedicated
pins as expected by PC monitors: this difference isn't something
that can be bridged by a passive cable but needs active electronics.
IRC, the Creator series have a separate composite sync.
I think the Indy's were SoG. I can't speak for any of the
older/smaller Sun 4's (or prior) as I've discarded everything
except SB2000/U60/SB150/etc. (I may still have a 128MB LX
hidden away somewhere -- always found the LX to be "cute")
Some PC monitors can accept the signal as-is but it tends to be
higher-end, professionally orientated models: commodity budget
monitors generally don't.
You may need to build a sync separator to get the signals into the
correct format. I do recall that there are at least a couple of
designs based on the LM1881 you could build yourself published
online. A quick Google should find them easily enough - I'm not
doing so myself since I'm working on a text console at the minute.
I've already got some passive adapters that work. The reason
behind my initial post (Jan 2012) was to find a source of
additional adapters as the ones I have don't seem to bear
much by way of identification (just molded blobs of plastic
with 13W3 and HDE15). With two heads in each machine, I
don't have enough adapters available...
