What you see on the photos is the floppy disk drive, however, I started with a tape recorder and it was a pain! I was also about to get the C64 first but the Atari could display up to 256 colors, the C64 had only 16.

I didn't know that about the colours! Of course I wasn't doing 'digital art' back then, just programming for fun. I think my first game on it was Jupiter Landing.

$0.05

I was doing digital art / animation and programming machine code (not assembly) on the C64. I spent so many weekends and nights on that thing... when I should have been doing school studies. I guess it worked out, because even when I finished school, none of the educational institutions had started teaching what I had already learnt.

I was so nerdy with programming, that my sisters could whip me at most games we had.

👍 gric, donnadavisart

[Assembler](https://en.wikipedia.org/wiki/Assembly_language) is machine code, only you use short *mnemonics* (symbolic machine code) for the processor commands instead of hex numbers.
Here is part of one of my Assembler codes for a game. I didn't have a printer so I had to write it down all by hand. On the screen I only got 40 x 30 characters which was too little to see the big picture for debugging. I actually started to write the code on paper before I typed it in.

Here is my game PhotonTrace (inspirad by the Tron movie) - I tested it today with my daughter on the 8-bit Atari emulator!
