So.. What is a scuzzygraph *exactly*
I came across this which gives more detail that I have seen elsewhere.. https://groups.google.com/forum/#!searchin/comp.sys.nsc.32k/scuzzygraph/comp.sys.nsc.32k/FW-BwmFo3BU/ytZR8Eu9PNIJ
In short.. the scuzzygraph is a TMS34010 purportedly the first programmable single chip graphics processor. The TMS34020 being similar with added FPU supporting up to 60million triangles per second. So that processor, at least 512k (up to 2MB) , a DAC, and assorted glue logic.
Knowing that... I wonder what the protocol is it sounds like it wouldn't be too terrible for someone knowledgeable to reverse engineer.

It may be possible to order this chip new from china.... a bit risky though its not supplied by anyone local.

Quoted the links incase vintage computer's site goes down.
"I also came across a port of binutils/gcc for the 34010 architecture done by Andrew Morton in 1994. This page has info:

but the links to the gsptools are broken. Fortunately, archive.org to the rescue:

It would seem to me that it would be possible to replicate a scsigraph in fpga.... with this much info on it. MAME also has emulation of it as it was in quite a few arcade machines. As far as the driver goes ask you'll have to ask in the *right places* to get it since I don't really know the copyright status on it. It would be nice to know more about the protocol it uses... apparently according to that usenet post there were people interested at the time in writing an X driver for it.
