  The SS5 drive. Something that does 512byte sectors.

  Nice. All the 530s and 2 of the 550s I've seen had full-height 5.25
drives. Noisy & expensive to spin.

  Service mode. You'll have to whack that lock before you can do much
of anything. Your terminal settings are right.
  I've used everything from a 6091-19 to an Idek Iiyama to an HP 20"
(98754A). Sync-on-green RGB, fixed frequency. There should be a paper
label on the adapter's bulkhead bracket with something like "1-1" or
"1-4" on it. Look it up in the MicroChannel Devices pdf at
http://www-1.ibm.com/servers/eserver/pseries/library/hardware_docs/
  That ought to give you sync & refresh rates.

  IBM cables for that 3W3 are rare as hell. Yes, Sridhar, I was sure
you had several. A DEC display cable will work if you swap Red for Blue
at the BNC end.

  I'll have to go find an ohmmeter - my lovely SO used it to see if a
flea-market lamp was getting fire at the socket. She thought mV meant
megavolts....

  Take the lock barrel out of the cabinet. If you're careful about how
you clamp it, it'll be more solid in the vise if you leave the lock
barrel in its bracket. Take the LED's PCB off. You want to drill a 4mm
hole into the face of the lock, just "above" the key slot. If you look
closely into the slot, you can see the brass tumbler pins. The goal is
to destroy them. Should you be apprehended, any knowledge of you or
your mission will be denied.
