I have 3 sticks of 256M PC2100 DDR RAM (ECC) from Crucial.
This is high quality server ram, that I bought for my machine,
before I realized that it was not ECC compatible. This is BNIB and unopened. Crucial "dot" com currently lists it at $79 and some change per stick. I'll take $37 per stick shipped, CONUS. $100 for the lot of them or trade the ram and some cash for a Kendrick SCT laser collimater.
