Assuming X can run on the card at all, it should be possible. Normally on non-OpenGL cards, the rendering is done in software, so it won't be terribly fast, but otherwise it should work.

but I'll step out of the way and let an Alpha guru explain further -- I don't have any real experience with Alphas myself.

There are no Linux drivers released for these cards, not even on X86.
These cards were made by Evans & Sutherland. At this point, they are about 6 or 7 years old already. Very nice at the time, if expensive.

If you can get X to work at all with one of these, it would only be as a generic VGA or SVGA perhaps. I wouldn't count on even that level of support though.

vga or svga are not even sure to work since the graphics card has to be initialized from the bios and since an Alpha does not have a PC-BIOS this could give problems...

I have a PowerStorm 3D30 in my AlphaStation 500/400MHz card but that is tga, if I am not totally far out. Any one got X working on that one? Exact specs for it?

Hello,

the Powerstorm 3D30 and 4D20 (TGA2) are not supported under Xfree/Xorg.
See the release notes from xorg.

VGA should work as a cirrus controller is responsible for VGA.

It seems, that BSD supports these cards - but I didn't tested it.

Yes, I've also heard rumours about hard core hackers enjoying X with their arcane graphic cards on BSD. However, after seeing stuff about 3D30 not being supported now and not in the foreseeable future on any other os:es I silently rested my case in favour of family life. Unfortunately, I can't really kill that dream of mine, getting the card working... But then it seems to be NetBSD.

I'm also childishly interested in the 3D google output thing in the back... But getting that to work is probably a challenge even for a NetBSD guru.

The TGA2 cards were supported in XFree86 at one time. DEC (or maybe it was Compaq by then) releasd the source for the drivers and Jay Estabrook got the driver working, sometime around 2000 iirc. I don't know if anyone has done any work to make them work with Xorg or not.

The 3D30 was a 2 MB/8 plane (256 color) card. The 4D20 had 16MB of memory (with Z buffer I believe) and 24 plane TrueColor, with 12 plane double buffer mode that did on board color dithering in that mode. It was pretty fast for 2D X and wireframe 3D at the time.
