It's really cool to design all those NOR gates using thermionic valves, as shown in the schematics in the middle of the article. I just wonder if using two regular diodes in the in…

I wonder if he really was afraid of the government, or if he was just tried to keep his brother from loading the games. The part where he actually cuts the physical tape is great. …

But he is still alive, isn't he? I hope he has heard the tunes by now. With sites like https://c64audio.com/ and Kickstarter projects like https://www.kickstarter.com/projects/c64a…

I smiled when I read the word "graphician" in the guidebook. That word doesn't really exist, or rather, it didn't exist until my scene group friend going by the handle OMG https://…

This, as a WebGL shader in shadertoy: https://www.shadertoy.com/view/ld23DW

Yes, it is very rewarding to program your own graphics routines or your own simple implementation of a raytracer and then see the correctly rendered scene on screen for the first t…

In 2013, I recreated the output as a shader in ShaderToy: https://www.shadertoy.com/view/ld23DW

"attention" sounds like "ä Tänn-schen" in German, which is Saxony dialect for "a small fir".

How many keys were there? I suppose there must have been a lot more keys than your ROM had address lines.

On 6502, JMP uses 3 cycles. A branch uses 3 cycles if no page boundary is crossed, and 4 cycles if a page boundary is crossed. So there, JMP is "faster".

So it's like "Cookie Clicker", but instead of baking cookies, you generate pixels like the VIC II chip in a Commodore 64. Great!

"Only legal opcodes were used in this demo" - Great! Some information on 'illegal' opcodes for the 6502 CPU: http://www.pagetable.com/?p=39 http://www.oxyron.de/html/opcodes02.html…
