Today I went to a customer with a rather old PC, this is the BIOS screen as it booted. It used to have 128mb of ram in but about 18 months ago I upgraded it to 512mb. It's slightly faster than it was! Check out the Pentium 3 processor running at 500Mhz. Suffice to say each reboot cycle of XP took about 10 mins!
Anyway I managed to fit a ethernet card in it and connect it to their BT Homehub and get it back on the intenet.
