unknown ram

Does anyone know what pc-100 h-sd ram and pc- 100-222-60120 ram will fit? I bought it used, and can't seem to get it to work in optiplex. Could probably use it if I can find out what it fits. Any help would be appreciated. Bought a pig in a poke cheap, as usual. It's supposed to be sdram, but can't get it to work on 7 different old dell computers.

Thanks. Google kept returning german with an apple every now and then, so my fears are realized. Guess I will pick an apple.
