First off, my apologies for posting this from my non-work email address.

The AS/400 (now named iSeries) is and always has been produced in
Rochester Minnesota. The RS/6000 (now named pSeries) is designed
in Austin. Both the AS/400 and the RS/6000 are manufactured in
Rochester. As of some model which escapes me now, both AS/400 and
RS/6000 computers use the *same* PowerPC processor. The only
difference is that the AS/400 runs the processor in "tags active"
mode (ie, the 65th tag bit enabled). The first PowerPC processors
used in the AS/400 was designed here in Rochester. Follow-ons were
designed in Austin.

Due to the fact that the AS/400 has 1 address space shared by all
processes, several restrictions have been implemented. The main
restriction regarding your statement above is that *all* code that runs
on the AS/400 is compiled by the "trusted" translator (an exception
would be our Java JIT). This means you cannot create a binary with gcc
and hope to run it on the AS/400. However, you may use gcc to produce
MI instructions which can then be passed to the trusted translator.
