I happen to have the guts for a 2MB IN-1670 memory system for the
PDP-11/70 - backplane and cards, but no box and no PSU.


It's a stack of 16 memory cards covered in 4116 DRAMs and a couple of
control/management  boards that cable over to the 11/70 the same way a
DEC MK11 box does.

Excellent reference.  A couple years too old for my DEC memor system,
but I happen to have a tray of MSC-4 parts and some early SRAMs,
DRAMs, and EPROMs documented there.
