I was about to say. DDR 2/3 I can still see many use cases for that stuff in modern-ish tech.

I am currently looking for some EDO sticks for a really well preserved IBM Aptiva I found on the side of the road. That stuff is expensive for a very different reason.

There might be some Aptiva EDO RAM sitting in my parents basement... Ill have to look next time im out there. Im not sure if I ripped it out and stored it before we sent the computer off to recycling eons ago.
