Assembly #03: Intro to 6502 Instruction Set

This video introduces the 56 op-codes in the 6502 assembly language instruction set, and gives examples of the commonly used ones, using a Commodore 128 monitor. Here’s the list of op-codes divided up by function. This is the third video in my ongoing 6502 assembly language series. If you’re not familiar with the 6502 hardware, or with binary math and bitwise operations, check out the two previous videos in the series for info on those.

Intro to 6502 Assembly Language Programming

I plan to do some demonstrations of assembly language programming, so I thought I’d do a short intro. This is about the 6502 family of microprocessors, which were used in many computers of the 1980s, and are still produced by the millions for embedded hardware and hobby projects. The 6502 is a pretty easy CPU to program, because it has a fairly small set of instructions, and yet it’s powerful enough to do interesting things.
