I have heard that Cyberstorm 060's require the Buster 11, as a minimum.
Not true at all. I've ran a CS MK III and a PPC in my A3000 for years with only a Buster 7 chip, with no problems. I only put a rev 11 in because I got it for free. The Ramsey and DMAC are both original in mine even still. You wont find a DMAC for a fair price, but you can use the newest Ramsey with the older DMAC even though they say you cant. I've seen several A3000 users do it with no problems again.
