I update article related to the byte number printing (https://t.co/iOaUgJsUCt). I found a big mistake I have made when I used BPL branch instruction on operations, which were done on unsigned numbers… Something I have no idea before I have try to use number larger than 127 :)

All my #c64 samples I have created during trying to learn #Assembler I am pushing to the public Git: https://t.co/Bgi7mVyOLr

The next #c64 article is about indirect indexed addressing (instructions like "STA ($FB),Y") and its use to print the simple ASCII ART to the screen: https://t.co/Ikb6BHKwHf

I just published “C=64 Part 3: Printing a byte number” https://t.co/72QEpdV9ts

@marcelsasik That's what I am trying to do - learning by programming small examples and reading about C64 and NES architecture... I loved playing games on those machines and now I am exited by doing first coding:)

There is 2nd #C64 piece of code - marco that places text on position [0,0]: https://t.co/XGDlwUmNXJ. I use it to print HELLO WORLD!

I hope one day I will understand assembler enough good to fix all those "first steps" codes ...
