The z80 is also still in use as a microcontroller of sorts.

Hmmm, I'm alway really surprised when people comment on threads like this.

How much time did you take to do this, I can read code, but I simply can't casually take a look at code like this and say, hey that's cool, hey that's interesting, I have to concentrate and go line by line, a more debugging state of mind.

There are programmers that can sort of skim read code which just amazes me.

6502 is also what the Terminator ran. We should thank our time traveler saviors for stopping the Furby uprising from happening.

A-116 Diag7.asm. Really if you got to page 45, you got through almost half. A-126 and on is just data tables.

> Surprisingly sophisticated.

I distinctly remember them being advertised as intelligent little friends who learn about you.

Western Design Center still apparently sells millions of 6502 cores each year. Especially for devices like this. So it's quite possible this was properly licensed and WDC provided 6502 IP.

It looks like this is basically a 6502 with no Y register and a reduced set of instructions.
