Regrettably I cannot assist as me and my portable Mac OS Box will be out
of the country.
But if nothing else is available, I could subsequently bring mine over
to a knowledgeable person who lives within 50 miles of Windsor.

Only a week ago I gave RPCEmu another thrash under OS X. But I got
nowhere as networking is not available for this emulation (see
<http://www.marutan.net/rpcemu/>) and also nothing I did would port any
RISC OS software to that emulator.
