The XP Project

Compaq LTE 5400

150 Mhz Intel Pentium & 80 MB RAM

It runs! The bare minimum xp requirements state a 233 Mhz cpu and 64 mb of ram, but it will run on a 150 Mhz cpu. You would need the patience of a saint to use this as your main PC, even the menu has a noticeable lag.

The lines only appear in the screenshots. Apparently the poor PC was so taxed by windows it choked doing screenshots.
