Learn a little assembly language for the 6502 processor

Who knew people were still using this?

We did note this one earlier, on first release: viewtopic.php?f=2&t=2222

However, a new surge of interest is welcome: I believe the emulator now passes Klaus' testsuite, and other bugs have been fixed too.

Cheers
