PC and other devices are
able to use double side SIMMs in most of the cases.
EDO RAMs work very similar to FPM RAMs and it have the ability to work within a page like FPM
RAMs. The primary advantage with EDO RAMs over FPM RAMs is that EDO RAMs hold the data valid even after the signal that "strobes" the column address goes inactive. This allows faster microprocessors to manage time more efficiently, performing many tasks without having to attend to slower memory.
Some Amiga turboboards and some PCs are able to use these advantages. Some times
there is compatibility with EDO, but devices can't take advantage of.
Memory chips are in both sides (double side). Depending of your socket, you will
be able to plug-in or not.
In Amiga computers, this memory are plugged in accelerators (also named
turboboards) or other expansion cards usually. The most of the turboboards are
compatible with double side SIMMs. 70ns is the common speed. 60ns take advantage
of some accelerators models as Blizzards or PPCs.
