[eAkGBG]

Ok I'm trying to get it to run.
Downloaded nekoware version it only gives me black screen and sound from demo playing.
Found original sgi version it will run OpenGL but extremely slowly. like 0.5 fps or something if I tune down settings.
I tried software version it just gives me strange colors and strange aspect of picture. But seems to run pretty much ok frame rate. 
I could live with geting sw quake to run.

But I really want playable quake world and quake 2 if at all possible quake 3

My hardware is single r10k 250mhz 1gig ram the esi board without texture memory.

Need some guidance here I need to play Quake on my retro machines

Edit:Solved
If you get crazy colors trying to run software quake upgrade irix to 6.5.30 then everything is good. the original sgi quake release will work.
