PDP-11/84 & Cipher tape drive questions

Lets start with the PDP-11/84... What is that console distribution board
connected to the DB-25 port in the back? Remote power control, dumb
terminal or what? What's the pinout of the connector? And about
terminals... What do I need to hook up a dumb terminal? It'll be either a
VT-220(after a good cleaning of the keyboard and a switch or two replaced)
or WY-99GT. OK, when I turn on the system the DC on light turns on and the
LED's just show a boring "77" every time... What does that mean? Anyone
have a list of error codes for the 11/84?

And then Cipher... Got two of them actually, the nicer one is labeled as an
IBM 4968(goes with my IBM Series/1). The big noisy one says it's a Cipher
0920640-98-125OU. So, what kind of interface do I need to hook it up to my
11/84? And is there any easy way to use them with a PC or Mac? And while
I'm talking about drives, does anyone in the PDX area have any cheap or
free drives or Unibus cards laying around they don't need?
