Hi,
Surely they didn't use the 6809 for the 3D
calculations, did they?
No, the 3D calculations were done by the so called "math box". This is
essentially a math co-processor made up of several (4?) AMD bit-slice
CPUs.
Yes, four.
What is a "bit-slice" CPU? How does it differ from, say, the 8086?
It's made of bit-slice logic chips. I don't think you can necessarily
call them microprocessors. I believe the most popular chips were of the
AMD Am2900 family. I've used them myself. They're righteous.
