I hope this is the only issue (high probability!). Reading the HP-70 ROM by not touching the precious hardware was very complicated and obviously this escaped my verifying.

Thanks for discovering that!

I assume we will see another teenix HP-70 emulator tomorrow

Thanks for the reply and for making the code available

Yes I can imagine those nervous surgeon hands.

Already uploaded, how could I resist :-)

I found it interesting that after scrounging the general operating system and the mathematical routines from the HP80 and writing the rest of the microcode for the HP70 differences myself, that my code used 325 less ROM words and 1 less RAM and yet offers the same functionality.

Maybe I could have got a job at HP way back then ;-)

cheers
