Let’s make a PC’s VGA card do odd things it was never designed for. #MSDOS #VGA #RetroComputing #Graphics https://ncot.uk/projects/dosdev/mode-x-madness/ Sat, 22 Mar 2025 14:35:37 +0000 https://ncot.uk/projects/dosdev/mode-x-madness/ After learning about Mode 13h last time, I’ve been digging about in the ancient tomes of wisdom and discovered Mode-X.

I’ve got a whole 320x200 pixel screen, 256 colours and direct access to the video card. No APIs, no helper functions. Just me and the video RAM. #MSDOS #VGA #RetroComputing #Graphics https://ncot.uk/projects/dosdev/lets-recreate-a-90s-pc-bios-boot-screen-part2/ Sun, 23 Feb 2025 12:48:31 +0000 https://ncot.uk/projects/dosdev/lets-recreate-a-90s-pc-bios-boot-screen-part2/ Thanks to @hobbified on YouTube, making the EPA logo look correct was quite straight forward… #MSDOS #VGA #RetroComputing #Graphics https://ncot.uk/projects/dosdev/lets-recreate-a-90s-pc-bios-boot-screen/ Fri, 13 Dec 2024 12:48:31 +0000 https://ncot.uk/projects/dosdev/lets-recreate-a-90s-pc-bios-boot-screen/ Because why not, it looks simpler than it really is and we’ll get to fall down a rabbit hole trying to draw the Energy Star logo. #MSDOS #DJGPP #VGA #Interrupts https://ncot.uk/videos/nostalgic-dos-development-part-1-freedos-djgpp-rhide-and-other-madness/ Mon, 25 Nov 2024 22:06:11 +0000 https://ncot.uk/videos/nostalgic-dos-development-part-1-freedos-djgpp-rhide-and-other-madness/ Come back to a time when 640k was enough, and when a 486 DX2/66 was considered a fast computer. None of this modern multi-core rubbish or branch predicting exploitable nonsense here. Just you, me, DOS and a C compiler. #MSDOS #DJGPP #CProgramming #AssemblyLanguage https://ncot.uk/blog-posts/rc2014-raspberry-pi-pico-vga-terminal-self-build/ Wed, 26 Jul 2023 19:39:57 +0000 https://ncot.uk/blog-posts/rc2014-raspberry-pi-pico-vga-terminal-self-build/ The RC2014 is a DIY Z80 based computer that talks to the outside world using serial comms. 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
