I recreated the demo computer setup by #lft (aka #lftkryo) using a #rp2350 microcontroller. For long time, it did not work. The VSync wire was connected to the wrong pin. Kids quickly pointed out that there is no sound (they like the music track of the demo). Yes, I still need to get some capacitors. Fun fact: the power consumption is so low that the battery pack does not sense it as a load, so it switches off after some time. #demoscene #retrocomputing Here is the original video... https://www.youtube.com/watch?v=KhhLoVBpg48
