[Premium-Rx] Norlin parts

[Terry O']

Mopping up after the Karski fest, I found some Norlin/ Applied 
Communication modules, blanks and extruded aluminum module shells in a 
box.  The parts numbers for the modules are:

SP-2101A, Assembly AD6847
SP-2102, Assembly AD5554, Rev G
SP-2102R, Assembly AD4993

Three of the blank boards are marked BS2000 PC
On blank is marked BS2001 PC

Also in the box was an Applied Communications "Work Order Traveler Card" 
which has little useful information but on which someone wrote with a 
Sharpie "SDU Cards"

Anybody know in what unit these were used?  Does anyone need them?

I can send pictures.
