I just bought 64MB of PC100 off e-bay, but yeah the guy didn't say anything about it being ecc or registered (even though it is), and as such it won't work with the computer I wanted to throw it in. It is IBM memory, HP part number D6097A if you want to look it up online (the whole part number is D6097-69001)

I really don't have any use for it, so if anyone wants it I'll sell it to you for $8, which is what I bought it for with shipping. tah013@umr.edu for more info. (Also, I should be in town either this weekend or next if anyone is interested, if not I can just sell it when school starts again.)
