Thin monitor for Sparc20??

Thin monitor for Sparc20??

Post by jk » Thu, 28 Apr 2005 00:19:41


Once upon a time I was a sysadmin, now I just have a sparc20 at home
that I use for personal stuff. I'd like to dump the 50 ton monitor and
get a nice thin one. I've seen some nice ones for the newer solaris
boxes. Will one of those work on my sparc20? anyone have specific
models that I should look for?

Thanks

I'd be careful, at least look into try-before-you-buy, maybe borrow one from
someboady. Or at least make sure you can return it.

I'm sure others more experienced than me traveled down this path but a
couple things off the top of my head.

You'll need a conversion dongle/adapter thing to change that common rgb
coaxial sparc output to vga. One problem here is, although the adapter is
common, it's analog out, many LCD monitors (which I guess is what you want
to use) is DVI only (digital). Some are both (can use a dvi to vga cable),
some even have a db15 vga connector.

So with that, don't get one that is DVI only.

The other problem I can think of is a number of LCD monitors are kind of
fixed-frequency. In other words, there is a specific scan rate/resolution
and refresh that is native. Although in the specs it says it could support
others, the picture looks like crap, jagged edges and stuff. Maybe they up
(or down) convert the incoming signal to match. Point is, just doesn't look
right.

Now it's totally possible there is some combination of video cards
(framebuffers, whatever) and doing this correctly, but I suspect with
something as old as the SS20, you aren't going to have many options to play
with.

Also possible someone is going to follow this up with a "all you need is a
506-xxxx card" and change this or that from console, but maybe not.

What you might want to do as an alternative is look around for a known, good
regular analog monitor (like a mits diamond plus 200). Something like that
is 21" and probably 1/3rd smaller than the 17" Sun monitor you have now in
the cabinet size.

Not much in reducing real estate and you'll still need the adapter but they
lock on the signal and seems like a step up from the Sun hardware.

They won't have that remote like some of the fancy Suns do, but considering
I never figured a use for it, no great loss. Wonder what *** the engineer
was on when they came up with that idea.

I'd agree with all of the above advice.

I've had success with NEC flat panel LCDs on Sun 13W3 connected cards,
including the turbo GX, and I currently use two monitors side-by-side on
an Ultra60 with two elite m6 cards. They are able to work with "Sun
synch" even though the on-card sensing on the elite m6 will not show
compatibility with a afbconfig query.

Look around on ebay and see if you can find a fugitsu AG-10e card. It's
about the best video available for the S bus / Sparc20 giving 24bit color
depth at 1280x1024 with about ~28MB video memory (if I remember correctly)
at reasonable speed. One of these and a 17-20" NEC flat panel and your're
good to go. If you have not done it already, also look on Ebay for a pair of
150-200MHz Ross hypersparc CPUs for your Sparc20. They will give you
quite a bit more get up and go compared with the original 80MHz superSparc
CPUs.
