IBM 36 diagnostic diskettes ?

[bsdphk]

I have digitized a pair of IBM/36 diagnostic diskettes (Soon to appear in Datamuseum.dk's bitarchive) but the labels are really something, so I wonder if anybody here know what the story is ?

The green one contains a volume named "DIAG51" with owner "IBMROCHESTERMN" and system-code "IBMSYSTEM/36" and a
single file named "DATASETIDENTIFIER" which again seems to hold:

* "DIAG51 Release 3.0"
* Non_CSIPL Diskette Program 2
* 3262 Printer I/O Module
* Microcode Patch Table
* CSU Tape Transient
etc.

The other floppy, with the big question-mark, contains a volume named "CUPID", system-code "IBMSYSTEMXX" with owner "IBM3234002 EC8" with
a single file named "DATA" containing test-patterns.

Is this simply how IBM tried to prevent their field engineers from overwriting the disk containing the diagnostics ?

Is your question about the meaning of the adhesive label/sticker, or the data on the diskette? Can you clarify your question?

I'm wondering about the green checkmark and the light brown question-mark.
