Ahh, I know those - we've got a set at Bletchley covering the various 
Natsemi chips.

Unfortunately I can't see the 32016 ref manual on bitsavers now - just 
the databook (which you have) at 70MB, plus various other odds and ends. 
No idea why it's no longer there; I'm sure it was there I got it from! I 
don't have it here on the laptop with me either, just on the PC back home :/

I do have a scan of the ACW 32000 assembler manual here - but it tells 
you to go get a copy of the natsemi 32000 instruction set manual from 
your local Acorn dealer, grrr! :-)

well, yeah ;)  Maybe it's one of those cases where it takes ages to 
understand it all properly, then suddenly a light goes on and it all 
makes perfect sense? Or maybe not :)

Back in 4 weeks so can have a look for the refman then if needs be... 
I'll also find out who sent it to me and originally uploaded it to 
bitsavers so I can give them a prod and see where they got to with their 
emulator...

cheers
