I got this on a P2/225. Win98. Trident 9440 graphics card.
It runs most other S/W fine.
I also ran siome diagnostics on it (HotCPU, CPUBurn, Perftest, all Freeware/Shareware S/W) with no problems.
Yes, it's an old CPU/graphics card, however it's been retired from the front lines to a games/backup machine.

Bob,
You'll have to upgrade the graphics card.
Celestia uses OpenGL, and Trident only supports OpenGL on their 9880, Blade, and later chips.
See their FAQ at
http://www.tridentmicro.com/site/go.asp?newsid=9&dest=drivers
The prereleases of 1.2.5 don't even work with OpenGL 1.1 or earlier, although v1.2.4 does work with many of the older versions of OpenGL.
Sorry.

That's not quite true, actually.
I had Celestia working previously on an even older processor using the same Trident 9440.
About a year ago, I had it working on a Cyrix Pr200, that had also been retired, in the same mobo and using the same 9440 graphics card. It was determined that the Cyrix was too slow to make it usable.
The Cyrix went to the bit bucket, and was replaced with the P2/MMX salvaged from another machine (nothing gets thrown out here at morlok's mishegas mansion ;-)).
So....
Relying on the fact that I had it working a year or so ago (actuially, last FEB), I tried to reconstruct what I had.
The only other thing I could think of was the revision of Celestia itself.
I found an older version of Celstia, V1.2.2 at:
http://prdownloads.sourceforge.net/cele ... e?download
and loaded it.
It works fine.
I don't quite understand why, as you said (and the Trident web site confirms) that the 9440 doesn't OFFICIALLY support OpenGL, but....
it works.
It's interesting that the older version, which (I assume) also uses OpenGL, works but 1.2.4 doesn't. It's fun to speculate why.
I've played with it abit, and it runs markedly faster than the old Cyrix piece of stuff ;-)
One thing I've noticed (and I note that the subject appears in at least one other note posted in the forum) is that the screen is very dark. Even with the bright/contrast cranked to 11, some objects are barely visible; at 'normal' bright/contrast, objects like asteroids&comets are nearly invisible.
I wonder if the palette is somehow being set incorrectly, as other applications appear normal in brightness/contrast ('normal being a relative term).
BTW:
I found several sites that mention older versions, sourceforge was the one I selected because I had heard of it previously.
All in all, it is an excellent program..... at least the old version ;-)
It's a keeper.

Believe it or not, Celestia 1.2.5 even runs on my Commodore 64 in the basement;-)

It runs on the vic 20 too right?
I'm trying to teach the cavemen how to play scrabble, its uphill work. The only word they know is Uhh and they dont know how to spell it!
morlok,
I'm glad you found a version of Celestia that works.
Unfortunatley, Chris (the graphics expert who is the primary author of Celestia) has explained several times that he only has Nvidia cards, so he has to depend on the OpenGL drivers supplied by the other graphics chip vendors to be stamdard compliant.
The more recent versions of Celestia use more recent OpenGL features. This causes problems when Celestia is used with older libraries, even those for Nvidia cards. For example, Celestia v1.2.4 work fine, although slowly, with the OpenGL v1.1 drivers supplied with Windows XP for Nvidia cards, but v1.2.5 crashes immediately. V1.2.5 works fine when Nvidia's OpenGL 1.4 libraries are installed on the same system, however.
As a result, those of us who have become addicted to Celestia have been forced to upgrade to Nvidia cards of various models.
