The suitcase makes me think in some kind of testing device for use of IBM
technicians. But I didn't see one like this in all my time in the Mainframe
division of my enterprise.

Looks like a 901X-002 Maintenance Device, for testing units such as a
3380 DASD. I have one, but no floppy and no documentation.

The floppies and documentation go with the controllers / dasd units, not
the suitcase.
buy a 3380 / 3880 / 3370 and you'll have one.
also there is a tape drive I think which takes the unit.
I think the document you use is the MLM if memory serves. there is a
ladder diagram thru the document that you follow that should lead you to
whatever conclusion you need if you are diagnosing a problem.

New subject: IMSAI 8080 Front Panel on Ebay
Blatant plug:
Ebay #110793243680
Unused IMSAI 8080 Front Panel, wired for optional Memory Protect
switch. The former owner was going to use this for a S100 project, but
never got around to it.

Where I work our 3480 drive controllers had an MD like that. The drives and
controllers are gone, but the MD is still in the CE room. Unfortunately at
some point someone left the disk in it and closed the lid, which folded the
disk in half. :-(

Were I to hazard a guess, I would say a telco tester but did IBM make
telco boxes?
