Amongst the things which I saved from the skip I have 4 IBM 8" floppies,
the labels say:

MAP ENTRY DISKETTE **M.T.=5412**
P/N=4410338 E.C.=571989 DIAGN.DISK. 1
--------------------------------------------------------
CONTENTS, 0D0-FFB-FFF-FD6-143-FC0,DD6,D44,
          FC2,DD9,C17-FA0,FA6,FA7
--------------------------------------------------------



STAND ALONE DISKETTE **M.T.=5412**
P/N=4247991 E.C.=571931 DIAGN.DISK. 2
--------------------------------------------------------
CONTENTS, LDR-FC0,LD5-FA0,E0A

--------------------------------------------------------


3340 MICRO DIAGNOSTIC DISKETTE **M.T.=5412**
P/N=4247992 E.C.=571989 DIAGN.DISK. 3

--------------------------------------------------------
CONTENTS, C16-FA1-FA2-FA3-FA4-FA5

--------------------------------------------------------


3340 DIAGNOSTIC DISKETTE **M.T.=5412**
P/N=4247993 E.C.=571931 DIAGN.DISK. 4

--------------------------------------------------------
CONTENTS, C11,C12,C14,C15,C17-FA0,C18,C19,
          C1A,C1B,C1F
--------------------------------------------------------

Can anyone tell me what these are and what they were for?

I realise that they were for diagnostics of some sort and assume that
the **M.T.=5412** is probably a machine type, but I am not familiar with
IBM's designation numbers.

At the bottom of the label is what I assume is a date in the format
77/01/05 - if my assumption is correct then these must be 30 years old.
