A couple of months ago I posted to various newsgroups to ask whether
DEC's OpenGL would work on the standard HX graphics system of my DEC
3000/300LX. A DEC engineer replied and said that DEC's OpenGL worked on
all graphics systems, using a software-only implementation if necessary.
So I ordered an Open3D license, which arrived today.
I just tried installing DEC Open3D 420 on my DEC 3000/300LX (with
standard HX graphics) running Digital UNIX 4.0. The subsets all
installed fine, and the GLX X server extension seems to be present, but
running xglinfo reports that *NONE* of the visuals support OpenGL.
Similarly, all other OpenGL apps report that they cannot find a suitable
What is the real situation regarding DEC's OpenGL and the HX graphics
system of the DEC 3000/300LX? Can DEC's OpenGL be made to work on this
Imagine that CRAY decides to make a personal computer. It contains 16
Alpha based processors executing in parallel, has 800 megabytes of RAM,
9 Gigabytes of disk storage, a resolution of 4096 x 4096 pixels, does
24bit 3D graphics in realtime, relies entirely on voice recognition for
input, fits in your shirt pocket and costs $300. What is the first
question the computer community asks?
"Is it DOS compatible?"
