A software thing I built: GPS on a 25MHz 486-SX

A user on a forum shared a project where they built a GPS system on a 25MHz 486-SX computer, using a $50 Raspberry Pi-like module and a GPS chip. The GPS module was connected to the 486-SX via a serial interface, and the user was able to display GPS coordinates on the computer screen. The user noted that the system was slow due to the 25MHz processor speed, but still functional. The user also mentioned that the GPS module's firmware was outdated, which caused issues with the system's accuracy.
