An Intro to 6502 Assembler

In the bad old days of the 80s and 90s computers weren’t as fast as they are now. You had to fill ’em up with leaded fuel and they were noisy and hot and you had to keep the windows open to let the fumes out.

Well, maybe not. They weren’t as fast as the handheld machines in our pockets now but I’ll bet that a larger percentage of users back then at least tried to code something. People had to because it wasn’t always easy to get games. You had to go down the shops and get out of the house to buy any new software! You had to open the manual to find out how to load anything!

So it was that I figured out that I’d rather be coding than playing games, and with the purchase of a book on assembly (that has sadly gone missing in the last year) I got busy and created a bunch of demos on the C64.

I wish I’d had this video to watch when I was starting out! If you’ve done any sort of assembly programming it won’t be anything new but it’s presented in an easy to understand manner and is worth watching if you’re at all curious about how computers work because a lot of the terminology is going to apply to other systems too.

I’m really looking forward to seeing the rest of this series. I want to get back to doing some assembly programming. There’s plenty of documentation out there but it’s a matter of finding the time and energy to do it.
