   I don't remember the exact wording but M.A.P. is IBM's term for the
troubleshooting/fault isolation flowchart. Some/all/most of the big IBMs
come with a MAP book that has the flowcharts in it. I'm guessing that the
disk contains some software that was needed for that. FWIW all of the big
IBM stuff that I've seen comes with one or more 8" (yes, 8 inch) floppy
disks that contain diagnostics and setup software. I have a MD-2
(Maintenance Device 2) that is used to operate and test many different
pieces of IBM equipment and it uses the 8" floppies. I don't know if IBM is
still sending out software on 8" disks but I do know that the MD-2 is still
a current item.
