Zap:

the 7600 has all the same effects as the 8000 but just not the surround versions right?

The 7600 has essentially all the stereo programs, and some stereo versions of the multichannel effects of the H8000. Note the use of the modifiers "essentially" and "some". For the reasons that will be obvious to you it does not have the surround effects.

Zap:

the effects are taken from the 8000 and the eclipse.  what about any from the 7600?

Since the 7600 and H8000 stereo effects are usually the same, there is no particular difference. Note that the Space effects are based on these – does not mean that they are the same.
