(50G) [HPGCC3] DRAW3DMATRIX replacement with grayscale surfaces, proof of concept

[Murray]

Hi,
I'd be really interested for some hints as to how to get HPGCC3 to work. I've built the HPGCCROM.bin on three different versions of Ubuntu ( and 4 different versions of GCC) - I can get it to build and the helloworld example, and the other examples to compile. While they run somewhat, they display distorted text on the screen and hang X49GP... But DRAW3D works, as far as I can see and exits cleanly, so there is something I'm missing. I would be grateful for any hints, or a walk-thru.
