Hi I currently have a Mac Performa 636CD with system 7.5 on it.

Today I saw an iMac DV grape for $35. The best I can tell, the DV originally had 8.6 on it. Is 8.6 backwards compatible with any system 7 programs?

I'm just wondering, as I have a whole bunch of System 7 programs. Also, even if it isn't, is an iMac DV worth $35 if it's in good working order?
