NetBSD 10.x Kernel Math_emulation
(wordpress.com)
This is my battle-worn, falling-apart laptop rocking an #i486SX CPU from the early ’90s. It’s so ancient that it doesn’t even have an FPU (Actually, that’s not true, they just cut-out FPU from i486DX to make CPU cheaper)! Anyway, I’ve always dreamed of running a modern UNIX-like OS on it.So, I spent some time resurrecting math emulation in the #NetBSD-10.x kernel, and guess what? I did it!
