That's rather difficult at very best. Very few places I know both to spend the money for the equipment necessary to detect the difference. Quite normally, if you hold the module up with the plugin portion pointing down you will see two small slots separating the plugin. Have the short end to your right. look in the upper right hand corner of the board. If there is a very small chip there, good chances are it is FPM. The others that do not, should be EDO. As far as detecting the chip speed, you need equipment to do it or have the Mfg part number to research it.
I collect any and all Mac pieces, parts and or systems that people want to get rid of. Referb and upgrade them the best that I can with what I have. When putting the memory back in them, I compare all the memory boards that I have which will work in that machine. If I can't fill it up with like boards I will purchase them all at once from the same place. This is also done when I receive them, they are compared to each other to make sure they are the same. If not I sent them back and tell them to correct it. It may irritate them, but makes my life easier when I give to computer to a family that has no computer knowledge. Fred....
