I don't know if the "HP 1000 F-Series Computer Installation and
Service Manual", part number 02111-90002 is available on Bitsavers.
You can find it here:

Figures 1-2 and 1-3 show the difference between the 2111F and 2117F
and how the two FPP Arithmetic and Control PCAs fit into the top of
the 2111F instead of into a separate box below the 2117F.
