RS6000 7012-320H

Today I finally had time to play with the Powerserver 320H
that I found a few days ago. I disassembled the thing and
circumvented the keylock switch issue (I was able to pull the
keylock pistons away without destroying anything) and plugged
a terminal to it in serial port #1.

1) It boots. The numeric diagnostic LEDs on front go through
  lots of messages, the HD spins up and does quite some work,
  I assume it checks the filesystems and so on. Finally,
  some initialization messages appear on the terminal;
  they seem to report on the very last stage of the
  rc script sequence (like bringing up tcp/ip and the like).
  I think that the serial console is recognized only after
  it switches to some multi-user run level.

2) It runs AIX version 3.

3) The SIMMs that I had talked about worked in this machine, so
   now it has 32MB instead of the original 16MB.

4) the login msg reads something like
   IBM AIX version 3 RS6000 (C) 1989, 1990
   Console Login:

How do I get inside?

Carlos.
