What I suddenly realised after posting is that the "LOW" ROM
stores all the even numbered bytes, and the "HIGH" ROM stores all
the odd numbered bytes, as the 32016 has a 16-bit data bus.
 
So, I would expect to find:
LO: "P", "N", "O", "A"
HI: "A", "D", "R"
 
Jules has emailed me the v2.00 ROMs, and by merging the two this
is exactly the case. It contains the strings:
 
Pandora 32000 V2.00     
Can't use OS_PRIV from user mode
Can't use OS_PRIV on OS_PRIV
Can't use OS_PRIV on unknown SVC
...etc...
 
However, on merging my ROM images, I think I must have imaged them
incorrectly as it contains:
 
TANDORE 72416 vevsmon 4.61
Ascape
...etc...
 
However, as the end of my images, there are the module SVC names:
 
...etc...
IdentifyRequired
HelpRequired
Program
Random
SetRandomSeed
Random Happy Xmas - Dave Keith Mark Kechil Simone Toby Trev!
 
which Jules's ROMs don't have, so it looks like mine are later
versions. Ho hum. Will have to dig the CoPro out after all.
