  Let's see, Mr. Holmes....

 The DC1127 is clearly marked (fuzzy photos notwithstanding) "Dual 8 Bit
Latch" on it's reverse.

    Might be a dual 8-bit latch of some kind...


The 66500 board says 'FDU Control' - Fixed Disk Unit? it has addr and
write enable switches... looks like a late 70s - early 80s era HP disc
I/O - for embedded test - network analyzers - ???


 The rest of the photos are so badly lit and out of focus that I can't
make out the designations - on the 6119 board - there is a crystal (the
oblong tin can) in the upper left corner - above that is some writing -
what does it say?


 Might be some treasures in here - also might be some gold scrap - some of
the boards have the 3-RU form factor HP used in a lot of their
early-digital era bench gear...


 Cheers

John
