I think Al said
he might have found some reference that proves that the IOP firmware was
actually ported by HP to the E. Can you confirm?

The part numbers for the E version appear in the 2000 section of the M/E/F CE
manual. It has 6 proms listed instead of 12. I still think it's possible to
convert the MX version to the E. Bob and Mike figured out what the instructions
do (from memory something like cnvrt isn't even used..)
