Amiga4k you dont know what the heck your talking about! I am sick to death of people stating the stock chips in an A3000 wont work with things.
I used my A3000 just up to 2003 with the only upgrade chip being the buster. I put in the 11 just for the heck of it and didnt ever have a problem before I upgraded it.
I used SEVERAL SCSI drives with my stock WD SCSI chip, never had a rev 8 in it
I used a CSPPC AND a Cyberstorm MK II and MK III in it for YEARS with no problems.
At the end it was in a Mirage tower with a Mediator PCI board, several PCI cards like a SB128, ethernet, Voodoo 3 video, TV and a Spider USB card. All with only the buster switched out. I also tried it with the stock buster just to see and it still worked fine.
My boot drive was a 4GB IBM SCSI drive on the stock SCSI, I had a catweasel ZII card with some IDE drives on it and a DVD burner on it. Again never had a problem.
So your system with 3.1 roms is fine and you can put just about anything in it. Look at my pictures here on Amiga.org to see my old system up close.
