Only the very first RISC based AS/400s where really different hardware,
by the turn of the century when the second generation of RS64 / Power3
systems where coming along there was already a lot of common hardware
between AS/400or iSeries and RS/6000 or pSeries only by Power5 time the
hardware was all the same except iSeries was still clinging to the IOP
but even that went away with Power 6 and even the support for Twinax WSC
is gone now since the last ones where PCI.
