So how can I make this even harder? How about I do literally everything myself, starting with nothing but a blank source file and write all the code by hand. No game engines or libraries. If I need something, I need to write it myself. And since we’re doing this the hard way, let’s write games for an… #AgonLight #Z80 #RetroComputing #GameDev https://ncot.uk/videos/forth-better-than-basic/ Mon, 16 Oct 2023 19:33:40 +0000 https://ncot.uk/videos/forth-better-than-basic/ Let’s look at FORTH, the obscure stack based programming language that nobody seems to use.

This means you need a serial interface to another computer in order to control it. #RC2014 #RaspberryPiPico #VGA #RaspberryPi https://ncot.uk/blog-posts/diy-vga-serial-terminal/ Thu, 08 Jun 2023 21:37:03 +0000 https://ncot.uk/blog-posts/diy-vga-serial-terminal/ I use a Raspberry Pi Pico and turn it into a serial terminal for my RC2014. #RC2014 #RaspberryPiPico #RaspberryPi #VGA https://ncot.uk/videos/clever-engineering-on-a-budget-zx-spectrum-interrupts/ Thu, 11 Aug 2022 00:00:00 +0000 https://ncot.uk/videos/clever-engineering-on-a-budget-zx-spectrum-interrupts/ How clever engineers made a cheap computer powerful #ZXSpectrum #Z80 #Interrupts #RetroComputing https://ncot.uk/videos/breaking-the-64k-barrier-spectrum-memory-banking/ Sun, 24 Jul 2022 00:00:00 +0000 https://ncot.uk/videos/breaking-the-64k-barrier-spectrum-memory-banking/ How do you get more than 64K of RAM in an 8 bit computer?
