VIC-20 Part 2 - Finally something

After a crazy week of searching forums,  downloading tools, setting the development environment, and of course "programming" in assembler and many, many, many, many, many, many, many, many, many, many, many errors I have finally something.  It is small and ugly, but it is here.

I put together a few 6502 assembler instructions to show a string on the top of the screen and change the border in the endless loop by switching between black and red color.  

After building it into a binary .prg file, it runs on the VICE (Versatile Commodore Emulator).

Besides the code itself, I made, what I consider an acceptable makefile and I explored a way of debugging the code using the command line Monitor tool, which is bundled with the VICE emulator. 

So there is some progress. With that speed and learning curve, I am afraid I will not be able before mid-2022 to display a circle on the screen.

I was thinking there might be another lost person, who plans doing the same, so in the future, I will put here a devlog about:

1. The .prg format and how to start the assembler code from BASIC, which is necessary unless loaded from the cartridge.
2. What tools I use and how I configured them

But now enjoy the video of the first release:
