I don't have the original code. I'm just guessing what the minimum
computations have to be.

The computation of the integer matrix ought to execute much faster without
using asm. Memory mapped video graphics on four hundred dollar eight bit
computers fifteen years ago could have done the graphics at least one
hundred times faster than my new computer if they had had the RAM. There are
very cryptic operating system techniques to graph quickly, but, I have
resolved to learn as little as possible about any operating system .
