Anyway, while extracting an off-topic device, I
came across a ring
binder that I had labelled 'HP9831 Manual' Inside were the 2 volumes of
user documentation for that machine -- the Operating/Programming Manual
and the I/O Manual.
I have at least two other manuals for the 9831:
BASIC Reference (09831-90010)
System Test (09831-90031)
Sounds like between us we have the full set :-)

Yes, the ROM is removable, so you can interchange the BASIC and HPL
ROMs on the same hardware platform.
That depends on the 9825. The later 9825s (I forget the suffix letter --
9825B or something) had no system ROM module slotted in the RHS. The ROMs
were on one of the memory boards inside, there was memory mapping logic
to allow 64K-ish of RAM _and_ all the ROMs to be present at the same
time. With those you can't stick the 9831 ROMs in.
Tony, have you looked at one of the 9831 OS ROMs? Do you think it could
be duplicated?
