Once apon a time I had a Amiga 3000 rev 9 motherboard running at 16 mhz, 3.9, CD rom drive, ethernet... and all was happy. And then I figured I would work to transfer all the new chips to my Amiga 3000 rev 7 25 mhz motherboard for a little extra speed. No hard drive has worked well on that other motherboard.
I have tried to verify all the jumper settings at...
http://www.l8r.net/technical/t-3000-jumpers.shtml But not sure I am reading it right. If anyone knows what a rev 7 25 mhz motherboard with the latest Amiga 3000 chips (Ramsey, Denise, etc etc..) should be set at, please do write it here.
Otherwise, what do you think? Should I transfer all back to the Rev 9 motherboard and just be glad it works?
One more quick question... I have a FAT GARY 390540*02 (3990) in this one. If I used an older one would this computer setup work alright?
I realize there are a lot of variables here, but just trying to put together and use the best that I have. I have 3-Amiga 3000's total, all of which I would like to get working. I would like to get this Rev 7 motherboard type working, probably because it was the first Amiga I picked up.

Thanks in advance to any advice given,
