No way, the biggest are 64MB and you need 4 of 'em to hit 256MB (the maximum he could ever run). @ philraz I know, it's crazy right? The old SIMMs are what kill old PCs, a shame really because even an old boat like Pentium2-350MHz will run PC100 or PC133 SDRAM. Makes all the difference. But I would spend $80 bucks on it or whatever, WTF. I like old computers, and the 200MHz could still work for some old lady or student or someone... But yeah, LoL you spend money on it, it's still gonna be slow :^)
