I'll fill in with what I know for sure.  Maybe someone else will have some
more in depth knowlege.

I'm not sure about the differences of the 23 and 23+ but if you have a 
choice get the 23+.  The 24 is Unibus the 23's are Qbus.

The 44 has split I&D, and Unibus map.  The 45 does not.

>the 11/70, 11/73 and 11/84/83...

The 73 is a J11 chip set replacement for the 70.  In other words a 70
  on a chip.  Also is a Qbus.
The 84 is the current product line replacement for the 70 (Unibus), the
  83 is the Qbus/J11 version of the 84.
