    After thinking about it, I think you're right. I had forgoteen that I
had borrowed most of this book from a local dealer and copied it. It's
titled "HP's 3 1/2-inch Flexible Disk Drive Service Documentation". This
book seems to be designed to include all of the floppy drive manuals in one
book. It has tabs for several items including the 9114, the command set
docs and one with a manual titled "Section 1, The 3 1/2-inch Disk Drive".
That section covers the bare drive used in most of these drive units. As I
recall you had to order each section of the manual seaparately and you got
an appropriate tab with each section that you bought. Most sections look
like they were written seaparately so that they could be added into any
appropriate drive manual. I also have sections that I don't have tabs for.
One of them is for the HP 9123, another is for the floppy disk drive
section of the OLD WIDE HP 9133 and another is for the HP 9121 drives.

   FWIW I ordered the 9114 SM from HP and it cost about $50! AND it wasn't
very complete. It had no service info on the bare drive. I think the search
for that is what lead me to the local HP dealer (probably THE last
independent HP dealer.) He didn't have the 9114 docs but wanted them so I
made a copy of them for him and copied everything else that he had in his
book.

   BTW while looking at this manuals while replying to this I found a
dection in the 9114 manual that says that it respondes to the SS-80 and
FILBERT protocalls. I've heard some people on the HP Museum website say
that Filbert was the code name of the 9114 during developement but it
appears that it's a protocall and not a code name.


  Thanks for scanning and posting the command set docs. That's something
that's been needed for some time.
