8600 has all the same stuff as the 8500. In fact, the last of them, a 250 and a 300(604ev's), had a 100MHz bus and can be pushed almost as fast as a new Mac. The RCA jacks on the AV models 7x00 and 8x00 afford a wide range of inputs, wile leaving the mic/line-in jack open for other uses. I have a radio going to the line-in and a VCR on the RCA AV in/out on my 8500.
