This article describes the development of a software-based Floating-Point Unit (FPU) for the i486SX microprocessor, which lacks a dedicated FPU. The project aims to provide a solution for systems that require floating-point capabilities on the i486SX without the need for additional hardware.
First Release is Here!
I'm excited to announce the first release of i486SX_soft_FPU — a software FPU emulator for the classic Intel 486SX CPU, running on NetBSD 10!
This project brings floating-point support back to life for 486SX machines, even though modern NetBSD versions no longer natively support processors without a hardware FPU. If you're into retrocomputing, operating system hacking, or just love old-school hardware, check it out!

Let's keep these vintage machines alive!
