Not specifically, no. But the .RPT files might be reports - text files
or printed output, so they might provide a clue.
But I guess you have looked at them already and found no clues.

With FDM ("plastic glue gun") printers, this process typically
involves a program called a "slicer". You export the model from the 3D
modeling program (.amf, .wmf and .stl are the most common formats) and
input that into the slicer program, which "slices" the model into
layers, and outputs commands to the printer (commonly G-code) into a
text file. The text file is then transported to the printer (via
network, or modern sneakernet aka SDcard) where you load it and start
the printing process.

Common slicer programs are Cura
https://ultimaker.com/software/ultimaker-cura and PrusaSlicer
https://www.prusa3d.com/prusaslicer/
In general, it is easier to start with the slicer program recommended
/ supplied by the 3D printer manufacturer - they have taken the
guesswork out of the settings, which gives you better printing results
from the start.

If I have to choose between Cura and PrusaSlicer, I prefer PrusaSlicer
because it has an easier user interface.

I've used the FluxEngine to read 3.5 inch, 5.25 inch and 8 inch floppies.
I've used the GreasleWeazle to read 5.25 inch floppies so far.
I haven't tried either of them to write floppies yet.
The main difference in workflow is that the gw software only writes
one type of format - SCP, so you will need another tool to convert to
raw or a different format, if you can't use scp directly.

Currently, the thing I find most interesting right now is that the
FluxEngine software can use GreaseWeazle hardware (supposedly for most
things) - I haven't tested that yet.

Sometimes, the "stuck drive" problem can be overcome by a gentle
"whack" with the handle of a screwdriver or other non-metallic object
to the side of the hard drive, (hopefully) in the direction of spin of
the hard drive. I have done this a few times on 5.25 inch hard drives
at least. With success, Procedure: with the drive powered up, hold it,
and gently give it a whack on the side, in the direction you think it
should spin. If it doesn't work after one or two tries, try something
else.
Caveat: this might affect your drive negatively.

Re: 8-Update

FWIW, the easiest way to find out if somebody has made (or has tried
to make) replacement parts for anything that can be 3D-printed is to
go to thingiverse.com with your web browser.
And then search for whatever thing you need (search terms / words are
a separate subject, try as wide or as many as have time for.
When you find a part, look at pictures, comments, makes and so on to
try to figure out if this is a working part or just something somebody
has mad a 3D model of, and never tested.
Some relevant examples:

FreeBSD doesn't run *any* graphical user interface out of the box.
What you end up with after install of the FreeBSD OS is a console with
a login prompt.
As any _real_ operating system should be, IMNSHO.

After you have logged in, you can (of course) install Xorg and your
selection of desktop environments (or a wm + extras if you prefer
that) via the package system (or ports, if you prefer to wait for
compiling from source).

Your description doesn't mention it, so we need more details:
- did you build the P112 yourself, or did it come pre-assembled?
- has it been working before? Or is this your first time trying it?
- which version of the ROM does it have?

There doesn't seem to be any information about ICL terminals at the
Terminals wiki http://terminals-wiki.org/

But some information is found
http://computermuseum.informatik.uni-stuttgart.de/dev_en/icl1501/icl1501.html

looks like these are a bit more than terminals

FWIW, this is nothing new with Windows: when the switch from Windows
2000 to XP happened, a lot of HP printer owners (I don't know if it
was limited to HP, sorry) was stuck with printers without a working
driver.
Yes, I know this doesn't help.

Back in the old days (ok, 1985) I faced the same challenge. At $work
we were using a HP9826 (or another model from the HP98xx series) as an
ATS (automatic test station). It had a custom made rig with stepper
motors to turn knobs on the DUT (device under test). It also had
connectors to the control (think wired remote control) sockets for the
various DUT's, connectors to the instruments (HP-IB controlled), and a
printer. The whole thing ran a set of test programs written in Basic
(I think HP-BASIC 2.0). My colleagues soon found out that the test
programs could use some improvements, but unfortunately they were
secured. I was the go-to guy for anything that required programming a
computer, so I was asked to have a look at it. Luckily, I found the
program that the vendor (ok, the company that had put together the
ATS, this was a custom job) had used to secure the programs on one of
the floppies. And it wasn't secured. So it was quite easy for me to
understand what the program did, and change it. Then we had a way to
unsecure secured programs.
On my HP9826 page[1], in the 1985-11-22 entry (yes, the page is
written many years later) you will find a link to a PDF copy of a
printout of the program (I no longer have the program itself) and
these instructions:

Requirements: HP 9826 or HP 9836 with Basic 2.0 (or perhaps later)
Usage:
LOADSUB ALL FROM "UNSECURE"
END
UNSECURE
END
DELSUB UNSECURE
END
This unsecures the whole program. If you just want to unsecure a range
of line numbers, use UNSECURE(A, B), where A is starting line number
and B is ending line number.

So you will have to type in the program from the printout.
Also, it has not been tested on anything else than that machine which
ran Basic 2.0 (IIRC), so if HP changed anything in later versions, it
might not work.
YMMV

Some of us just want a working solution. So, any links for hardware,
software and an assembly description?

A Kryoflux would work, but since the software they provide isn't open
source, I can't compile it to work on the platform I use.

In general, kermit under Linux (and other unix-like operating systems)
expect you to start kermit from the terminal emulator of your choice,
and "inherits" whatever terminal emulation you have started it from.
FWIW, I've successfully done vt100 with kermit started from xterm.

Are you sure that your xterm has Tektronix graphics emlation compiled
in / enabled?
I haven't tested graphics emulation yet, because I don't have a
vintage machine that supports it.
