Problem solved. By resetting lots of parameters I got it to the stage
where it would boot properly from the green screen with the list of
startup options by choosing IDEFS drive 4.
 
I took the RiscPC to our local RiscOS group at Southampton where Andrew
Conroy went throught it with a fine tooth comb. He surmised (correctly)
that because I only used the machine sporadically, it hadn't been on for
enough time to recharge the CMOS battery so was losing its settings.
Andrew suggested a straight run of 8 hours per week should keep the
battery healthy.

He then checked for unplugged modules. None were unplugged. That
triggered my little grey cells. In the dim and distant past when I set up
the Unipod, I remember the Simtec instruction that if you put the CD Rom
drive on the unipod instead of the motherboard, you had to unplug
softATAPI.
Having lost the CMOS settings it had reverted to the default setting of
plugged in. 
ATAPI unplugged, machine back to normal. 

All now fine.
