Ah crap. I forgot that I only have Step 1 boards. These use the SCSI controller for DMA and I'll bet that thing is tricky to set up. No guarantees it will succeed on the actual board but we could develop some code anyway and try.
Best approach I think is to copy the data from one of VF3's viewport, including that all important matrix 0. Then figure out a way to display a single big triangle in the center of the screen.
Anyone want to try? A good way to test is to just hard code the data into Supermodel

Then I can try writing a program and testing it in emulation during my flight Tuesday.
