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!
Project page: https://github.com/mezantrop/i486SX_soft_FPU
Contributions, feedback, and testing are all very welcome!
Let's keep these vintage machines alive!
