Show HN: GentleOS – A pair of hobby OSes for vintage 32-bit and 16-bit PCs Hello HN, I've been working on a simple OS for tinkering and running bare metal apps on vintage PCs. Since I couldn't quite decide whether to target pure 16-bit, or slightly more capable 32-bit machines, I ended up with two separate versions: - GentleOS/32 ( https://ift.tt/6jGvrMi ) works on i386+, requires 4MB of RAM and VGA display supporting 640x480x16 mode or any 256-color VESA mode. - GentleOS/16 ( https://ift.tt/DKEdljh ) works on 80186+, requires less than 192KB of RAM and a CGA display supporting 320x200x4 mode. You can find more details in the repos. https://ift.tt/6jGvrMi June 7, 2026 at 10:45PM
