I did some checking on the internet, and the RAM looks like it is compatible with my PC. I already have two sticks of 256MB PC133 installed (slightly faster). A memory retailer indicates that it is OK to mix the PC100 and the PC133.
I am going to be away for a few days to attend the funeral of my mother, so I don't know if shipping arrangements can be made before I leave. If someone else is interested in your memory, I won't feel slighted if you send it to them.
