More HP microcode & loader rom detective work

I'm finally digging into my 21MX E-series machines in earnest. In trying to
inventory and document what all I may have, I've found a few things that
stump me and my "docs on hand". Perhaps folks here can shed some light on
these. Mostly I'm looking for "confirm or deny" on some points.

Loader roms I can't positively identify:

11B5790X012 This is in a system that has microcode roms
18A0580X012,18A0580X022,18A0580X032
I'm guessing something third party, or perhaps a later rev of DS/1000 or
loader extensions? I'm clueless on these.

1816-0420 No clue

12531LDR This is a hand written tag. Perhaps for loading from the teletype
builtin paper tape reader?

1816-0769 No clue

Microcode roms I can't identify:
1816-0996
1816-0997
1816-0998
1816-0999
1816-1000
1816-1001
93585-80006
93585-80007
93585-80008
18A0580X012
18A0580X022
18A0580X032

And lastly, I'm confused about FFP. I am guessing that FFP required FP,
which is supposed to be standard on E series. But a few lines in various
docs make me think that perhaps older rev E series didn't have FP built in.
Some docs mention that when ordering FFP, you can specify option -100 to get
some additional roms, necessary for E series machines with a serial number
less than 21XX (co-incidence on the rev number). I'm guessing that the
additional roms are FP? The roms in question are:

13306-80013
13306-80014
13306-80015
13306-80016
13306-80017
13306-80018

Can anyone confirm or deny this?

Thanks!

Jay West
