help with unknown cards

["Brett Smith" <caul@concentric.net>]

Hello,

I recently aquired 2 cards that go in a IIGS and was hoping someone could me
figure out what to do with them!
    One is a sound card of some type, it the name "Echo II" on it. It's a
small card and has a jack to plug a speaker into. Is this just a card to
output sound or is it a synth card of some kind? Do I need specific software
to access it and utilize it?
    The other card is an Orange Micro RamPak 4GS. I doesn't have 4 megs of
ram on it, however. It does have 28 empty slots for memory chips. Does
anyone know what kind of chips went into these slots and if I can still
obtain them somewhere?
    Again, any help is appreciated!


Thanks,

Brett Smith
