The 9672 has 2 PC's in it, one is a TP380 built into the box and the other is
an IBM PC300 which connects to the box via a Token Ring cable.  Both run OS/2.
Dunno why IBM still uses an external 2400 baud modem with the service processor,
there are a couple of empty adapter slots in it.

I actually have my own personal 9672, with peripherals; the company wanted to get
rid of it and I offered to haul it off, they said OK.  Perfectly functional box, I
personally shut it down.  It's in the basement.

As of about 2 years ago the service processors on IBM's big iron still ran OS/2.
