My opinion only, but I did at the time work for a company that created a TMS34010 product. It didn't take off because, frankly, it sucked. It was very expensive, relative to competing products, made worse by requiring lots of expensive VRAM memory (for both code and data memory) for decent performance. Memory bus was 16-bit, so if you were trying to do, say, 8-bit graphics, you could only grab 2 pixels per clock (~150ns-200ns depending on speed step). It was integer math only. I recall the C compiler was pretty buggy as well. There was a follow-on TMS34020 chip that was faster and had an FPU coprocessor and better 3D, but it was still prohibitively expensive to deliver product, and by then there were a boatload of competitors that were beating it on both performance and price.
