As for minimum hardware, Apple says the with the minimum install you should be able to run it on a SE/30 (68030/16MHz, 68882) with 8/80 (you would be missing alot of stuff though). I'm running it on a Quadra 700 (68040/25MHz) with 24/500. I would personally put the lower end at and 68030 with FPU or 68040 with at least 16/200. It should work great on all of the Centris 650, Quadra 610 and 650 systems as long as you have the Enabler for those systems that works with System 7 (I think you can still download those from Apple because you can still download System 7.0.1). As for the 660 and 840 series systems... I don't know. Those were very special systems that put them beyond the other Quadras and almost in the same league as the first generation Power Macs. I would guess that because 3.0.1 supports the Quadra 800, that it would also work with the 660 and 840 systems. But again, I really don't know for sure.
As for the LC III systems, they didn't have the 68882 FPU. The Mac IIsi had a card that you could get to add one, but I don't remember if the same was true for the LC systems.
(Note: the Centris 610 has a 68LC040 and would need to have it replaced with the 68040, which is what the Quadra 610 came with, in order to run A/UX).
