Speaking of boards vs boxes, any idea what an empty BA11-F fetches
these days?  I have a box with all the boards for a KB11-C (PDP-11/70)
including backplane and front panel PCB (no mounting bracket or front
plexi) and I'd like to turn it into a working machine if possible.

(I also have all the boards and backplane, and no box, for 2MB in-1670
Intel memory subsystem (eg

- just need to fabricate a box for that and add a fat PSU.  It has
over 1300 4116 DRAMs)

I would recommend adding somewhere a date for when the numbers were
last updated since prices will obviously change as time goes on.
Nothing wrong with giving out numbers, but provide them with a
"freshness date".

I have a number of BA23 boxes, and a BA123.  The next one up in the
series off the top of my head is the BA213.  I'm fuzzy after that
because we stopped buying DEC gear around that era.
