Over the years, I’ve looked for an Assembler for the VIC-20. Sure, there are great cross-assemblers like Kick Assembler, but I wanted something that would run on the VIC-20 itself.

I’ve done a lot of silly math, ciphers and asked a lot of my vintage hardware on this site over the years. But I’ve not talked a ton about optimizing code for faster results.

I was recently on a video call with a friend, throwing around some ideas for a new product. I mentioned adding large signed numbers in assembly and using two’s complement. He asked me what two’s complement was. I was a little surprised that he didn’t know. He’s been a Java programmer for more than 30 years. Java and Python programmers (and others like gasp Commodore / MicroSoft BASIC) don’t have a native unsigned integer type. The language takes care of the details for you.
