   I'm almost certain that the programs are stored in a tokenized format
and the "lesser" machines don't have all the BASIC commands that the 9845
does therefore they can't translate 9845 programs back into text. I read an
article about this somewhere in a HP manual. I think it was in one of the
HP 9845 manuals. I have some here at the house I'll look through them and
see if I can find it.
