There is: Obscure internal details of HP calculators

• Hex tables of internal byte codes for user program steps
  

Unfortunately, the HP-25 is missing.

Thanks, the 11C looks about like I was expecting, i.e. packed to the gills.

The 25 presumably had so many unused opcodes because every last byte of the ROM was filled, and there simply wasn't room to implement any more instructions!
