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

This is a project I wish I still had access to. It's something I worked on where I was asked to build a "real-time GPS-driven moving map display" -- what we simply call a "GPS" today. Only today it's built into virtually every cellphone and tablet computer in the world. I was asked to write this software so it ran on a hardware platform with a 25MHz 486-SX CPU, 32MB of RAM and the software would be in ROM. IIRC, the screen display was 1024x768. They gave me a laptop configured like that for testing.
