I've long thought that the AS/400 would be Really Fun to emulate.  The
virtual-machine nature of the architecture would seem to make it possible
to have an "emulated" AS/400 on amd64 that would be faster (in terms of
CPW) than anything before the POWER5-based iSeries systems.

I/O would still vary, but most of the smallish AS/400 systems didn't have
impressive I/O performance.

All that said, I don't know if the necessary documentation exists.  I'll
have to ask some of the ex-IBMers that work here if such a thing existed
where someone could've plausibly laid hands on it without an NDA.
