    • I too 'grew' up writing for the 6502, and the main reason we used assembler is that C was not a language in wide use yet, and when your cpu is only running at 1MHz,( yes, there really was a time when things ran that slow) every instruction counts. And even today C compilers for 8 bit parts leave a lot to be desired. I am a big proponent of the 90/10 rule. 90% of the time your program is running in 10% of the code. You optimize the 10%, whether by improving algorithms OR using hand coded assembly, and it will greatly improve the performance of your application with the minimum effort.
