Thanks guys. I was a little confused about the later ROM on the cache card and the 25mhz crystal that looks like a later add-on because it doesn't really sit onto the card with a correctly sized socket.

I will have to find one of those cables. I actually need to find an Apple IIgs to house these cards because my current IIgs (noted in this conquest) is full.  THAT, in my opinion, was a find of a lifetime.
