It is better to add a mode for real HP10.

That's very true :-)

Unfortunately, the HP-10 microcode is likely to stay a secret unless someone has a dead one with a known issue within the main CPU chip. All those secrets are contained inside with no external access so unless the chip was de-capped and the ROM contents read visibly, there will be no way of getting it.

I wrote my own working version of the HP-10 in HP microcode which is what I will be using. Mike has been helping lately as he found a few bugs which have now been worked through.
