Tried it in Richard's BeebEm v1.4.  Unfortunately, it won't boot,
clearing the screen then hanging the emulator with the cursor flashing
at the point where it was when I changed Options/BBC Model from BBC B to
Master.  Tried a few of the emulator CPU instruction options with no
luck.

If anyone wants to try the ROM images I extracted from FinMOS.rom,
they're available here:

http://www.astro.livjm.ac.uk/~mdt/FinMOS.zip

This extracts to give you the following:

mos.rom
dfs.rom
viewsht.rom
edit.rom
basic4.rom
adfs.rom
view.rom
terminal.rom

which can then be installed into BeebEm using RomMgr or by renaming
beebfile/M128, re-creating it and extracting the above files into it.


The method I used to split Pete's original 1Mbit (128k) FinMOS.rom file
into eight 16k ROMs as expected by BeebEm was:

cat FinMOS.rom | split -b 16384

on a Linux box.  

Looking at the resulting files using xxd gave credible-looking output:

I'd very much like to hear if anyone gets any further than I did.
