I searched but couldn't find anything that I needed. I picked up some MDDs(dual 1.25 & FW800 1ghz) with bad power supplies and eying up another MDD(Dual 867) which is working. Will the dual 1.25 and single 1ghz processor daughter card work on the previous model? I know the System clock is different and heard about removing a resister on the first gens to 167mhz FSB. I will also try and transplant the PSU too to check to see if my 2 MDDs fully work or not.
