I never had a TI 99-4, but I admired their graphics. A trip to a silicon valley electronics store netted the graphics chip used in the 99-4. I hand built a daughter board for my Heathkit H8 to interface the chips, then wrote all the graphics primitive libraries to drive it. Inside a week, I was doing 3D graphics plots in color with full Z axis support. It was Summer 1982. I couldn't afford a Mac Lisa, but I could compete with the graphics running HDOS or CP/M on my Z80 with 64k RAM.
This is an entire post of awesome!
