I disagree with the notion that certain OSes are meant for certain Macs, especially concerning II series and 6 only. I never liked System 6, it sucked pretty much from day one. Add that to the fact that 7 runs fine on most II's, and you have me happily running 7.6.1 on my IIsi and IIci. I consider running 6 on most Macs but the 68000's to be crippling them.
