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 . Cliff Nelson
