simply like this , EDO simms doesnt work in several cards , some cards dont like the simms because of fysical size.
also there is alot of "try before you buy" things as amiga cards (all) doesnt accept 50/55 NS simms nor 80NS simms ..
60ns is the best you can use in an amiga card!
Edo works only in a few cards (but it will be read as a normal 32bit simm)
so to your question.... read above
