I credit the BASIC and machine language byte code type-in programs for reinforcing my attention to detail and being able to track down software problems.

Kids these days[0] will never know the "pleasure" of spending hours typing in some cheesy BASIC game only to have to track down any number of syntax errors!

It's amazing that I still remember some opcodes like the ones you posted (and others, such as 0xAD for LDA$, 0x78 for SEI, 0x58 for CLI) after all these years. Brains are weird.

I don't remember the numeric codes unfortunately, but BEQ, BNE, JMP, JSR, ROL, ASL...
