Yeah seriously that's an ungodly amount of RAM for a PC of this vintage. My old WinMe machine had 128MB.
(And an 800Mhz PIII. I later added a GeForce 4 MX 4000 so I could actually play games at more than 15-20 FPS. It was my first graphics card purchase ever. Also upgraded to XP cause Me would BSoD so often that I never got a chance to do a proper shutdown at the end of the day. When the machine crashed, I was done for the day.)
