Let me thank everybody who put in advice on where to go with this. I went through 
a few cycles:

a. picked up an old ZIP100 parallel SCSI (20 euroes).
b. found a utility called EPSLIN (with source) that writes to the floppy or HDD and can
generate the proprietary formats. This does not work with USB FDD since it has to 
use some kernel calls that control the programming of the uC765 floppy controller
chip. With USB attached floppies this chip, or similar, is actually on the external
floppy so the kernel calls have no access.
c. Found bipolarisation.com who put the OS and factory disks on-line (have to thank
them too).
d. Formatted a ZIP100 SCSI (24 euroes for a pair of disks)
e. Copied the OS over.
f. Linked it up to the ASR.
g. Nothing. This is a pretty stupid ZIP drive - no options to terminate the SCSI or 
to select the device ID. Incompatible. Will sell it again.....

h. Got back online and got hold of a Dell floppy (15 Euroes)
i. Picked up some floppy disks (4 euroes for a box of 10).
j. Let's just make this one short - did not work in any of my 4 Dell laptops. It was
from the Latitude C series.

k. Got down to CashConverters, picked up an old Compaq desktop for 60 Euroes.
l. Put together a liveboot USB (quicker than downloading a live DVD)
m. Put a 32bit version of epslin on to the stick, put the ARS OS and the 8
factory disk images.
n. Formatted onto a really floppy disk drive.
o. copied the OS to it.
p. put the disk into the ASR10.

MAN, IT NOW BOOTS!

Working with floppies would normally be painful but until I can get hold of
an even older ZIP drive or some other parallel SCSI device it will do - I am
not going to be loading (m)any sounds, I just want the OS there spitting
midi out into bristol for the PolyPressure stuff.

Again, thanks for all the advice.

Am going to put out a bristol 0.60.11 which just fixes some build errata
using patches contributed to the project, then some time later I want to 
get the CS-80 emulator working as a 0.70 or similar. I will add options to
have PolyPressure track ChannelPressure as I know there are not many
keyboards out there with poly capabilities (also from this thread).
