Sun managers,

I received over 60 prompt responses on this subject,
thanks to everyone who answered!

Most people pointed me in the direction of a company
called Sunburst Computers. An email from eeimkey@eeiua.ericsson.se
(Martin Kelly) gave me a description of a product and
the necessary info to contact Sunburst, which I had already
done earlier this week via an email address given in a SunWorld
magazine advertisement.

Martin wrote;

"Have you seen The SPARC Presenter from Sunburst computers.

This includes a 640x480 resolution, 226,000 colour active matrix
projection panel with digital video and audio control. A Cyclops "eye"
wand and laser pointer with Sunburst integrated driver for X window
support under SunOS. All necessary hardware and software for connection
to Sparcstaions.

It costs in the region of US$10k.

Its avialable from the following address:

Sunburst Computers
187 Calle Magdalena
Encinitas
CA 92024
USA

Tel: (619) 633-1680
Fax: (619) 633-1169

e-mail: sales@sunburst.com"

Other companies mentioned where Barco, Sony, Electrohome,
Esprit, and GE.

The prices seem to start at around 10K US for most
of the projection units.

Some people also connected a projector to a Mac or
PC running X emmulation for their Sun workstation.

Following, are some of the responses I received that
might be helpfull to you:

I don't! We had a similar problem a while ago, and ended up using a
Mac running MacX, with an Overhead Projector tablet attatched. The sun
sent its output to an xterm running on the Mac. Did the job!

Daniel,

When I was network manager for Ohio State Univ. CS dept, we bought a Sony
unit. Excellent piceture. Barco also makes an excellent unit
The only unit I ever had a bad experience with was an Electrohome which
was very difficult to converge and setup.

Those are the three main names.

If you do some travelling for demos, consider a Tadpole SPARCbook. A
really portable Sun clone with VGA output. One o the advantages of the
VGA is that you can find projectors or LCD screens for overhead
projectors at most big conerence hotels. And the computer itself is
only about 3 kg (6.8 or 7 lbs)

Daniel,

        We have a projection television that I am told will take
direct feeds from a SUN workstation. I believe that it is an
Electrohome. I have also heard of LCD (overhead) projector
presentation systems from the likes of Sunburst Computer (San
Diego,CA). If this is the sort of thing you are interested in I
would be happy to get more complete information for you (addresses &
telephone #s etc)

There are 2 companies which I know of who makes such projectors:

   1) Sunburst Computers: their equipment work specifically with Sun
      SparcStations and they will even sell you a packaged deal with
      a Sparc along with the projector. For information and brochure,
      you can call them at 619-633-1680, or e-mail at sales@sunburst.com

   2) Electrohome projection Systems: these folks have quite a few
      models. You can contact them at (519) 744-7111.

Currently, in one of our labs we are using a Barco system, but we're
not very satisfied with it. The projection is extremely grainy and
from further than 10 feet away, you can't read much off the screen.
Barco probably has a better system by now but ... well, personally
I'm not impressed with the company or their support. Oh well, my
2 cents' worth.

Hope this helps.

I don't think you'll find anything on the market YET capable of the
same resolution as a standard Sun screen (1152x900); the technology
just isn't there. PCs are typically MUCH lower resolution. You CAN
get various projection devices which will either display a PORTION of
the screen, or will give you a screen with PC-like resolution.

That said, there are a couple of huge, expensive, data-grade projection
systems available. I know of Hughes, and I think NEC. They run
somewhere around $20,000 and up, though. We have a few, and they're
not very readable; they have to be VERY carefully focused by a
professional on a rigid screen, and never moved.

Electrohome makes a series of projectors that will project the image
off of a sun screen. They are quite pricey but work well.

There definitely is such equipment available, but probably not what you
are thinking. Those LCD overhead projector things are not yet big enough
to handle Sun's, but there are projection TV's that will work. We have one
here. Electrohome makes such a beast. They aren't cheap, but you can lease
one for ~$1000/month.

Daniel,
        I recall a little information concerning this when it was discussed
a while back in the comp.windows.x group. Some of it is x-specific, but
this may give you some companies to start looking at. Here's some excerpts:
Good luck.

Subject: Re: looking for X overhead projection system
Status: OR

Most of the "special hardware" is not CPU manufacturer specific but
rather it is display specific. My ubiquitous SONY display on my
RS/6000 (even though it has an IBM logo) has extra BNC connectors that
are "output" from the display. Our auditorum has some special
hardware ( I don't know who makes it) that allows attaching most
displays to the projection TV in the auditorum.

---------------------------------------------------------------------------

I use PC's running Hummingbird eXceed Plus software for X Terminal
emulation. I use Barco projectors in conference rooms to project the
images in conference rooms across the country.

I know PC-to-videotape equipment is available for reasonable (well,
sort of) prices. This might be your best approach, because competition
has brought PC hardware cost down and a high-end '386 can run X quite
acceptably. I'm using a PC running X now, with Super VGA and 800x600
resolution.

Of course, being a "dumb" terminal is about all a PC is good for, but
they work pretty well that way.

I am quite sure that Barco makes an overhead projection TV that should
handle any standard RGB monitor. I know that Electrohome does make one.
We tested one out against a Sun-3/60 with a color monitor. As I recall,
they have an adapter to use for monochrome monitors. The bad news: they
cost something like $20K. You might be able to rent one, though.

The best answer for accessing the video of an NCD that I know of is to contact a company in Los Angeles called Extron. They make a tap that goes between the monitor and base that I believe will answer almost any of these sorts of requests. The contact information is:

I have always found them to be very helpful.

Indeed, probably the most reasonable thing is to run X on a PC using one of those VGA/NTSC boards. I believe US Video makes one. There are several on the market. PC Mag did a review of such devices perhaps a year ago. The best you can probably do is run a 640x480 Windows driver. These boards then also put out NTSC as well as 60Hz video for a Multisync monitor. Of course if you wanted to videotape it with a standard VHS VCR, you're not going to get anything as good as 640x480. VHS is good to around 240 lines. S-VHS is good to about 400 lines. These boards cost about $500, I think. I seem to recall that Egghead is one distributor. Good RGB->NTSC converters start at about $1000 and go up. Another option is to screen dump the X windows image and display it on an NTSC frame buffer (after suitable reduction in resolution). Perhaps an Amiga would work. If you don't need color, this way may be the cheapest, since it should be possible to find a 30Hz 512x512 frame buffer somewhere and you can skip the NTSC conversion.

This is not quite what you asked for, but it serves the same purpose.

We use a video projector (Sony VPH-1030QM) that can directly be driven by RGB or NTCS. Our Sony is connected to a Sun with a TAAC-1, because the TAAC-1 can easily be configured for the low resolution this device needs (1024x512). The device is quite old, so Sony probably has better devices that cope with the resolution of common workstations directly. -- Arne Ludwig arne@rrzbu.hanse.de ...uunet!??????!rrzbu!arne
