Thanks for the reply, Mark. This PI is on circa 1994 Irix 5.3. Nope,
this cut of Blender is IrisGL, so I don't think that's it.
Certain stock Irix 5.3 demos don't work. Launching the MahJong is fine,
so is the flight sim. Launching the mandelbrot fractal maker is a no
go--says 24-bit is needed. The Porsche driving sim. comes up but puts
up an error message that says "gconfig: not enough bitplanes for RGB
mode."

Anybody have a PI graphics board that's 8-bit or better to give or
sell
to him?
There's something wrong here. I know of no SGI with less
than 8 bits of graphics, all the PIs have at least 8 bit
graphics, and most of them have 24. So the problem must
be somewhere else.
Here are a few things to look into:
1) Which version of the OS is it running? Some of the earlier
versions of IRIX used some of the bits for window management.
2) I don't know anything about blender, but is it expecting
OpenGL? The PI series doesn't run OpenGL, they run IRIS GL,
which isn't compatible with OpenGL. This could be where
the problem is occuring.
