    Used to program the 6502 then the 65C02 using the compiler Merlin. I could spend hours buried in assembly language routines, debugging and optimizing just to shave off a few microseconds. Loved it!

    This is amazing! I used to program in Z-80 and 8080 Assembly, and your source code is similar. I will visit your project for more details, because I'm interested in the architecture. I have subscribed and thumbs-up! P.S. This would look great with a flipdot display!
