HP97 The journey begins

[teenix]

Hi all,

I've managed to get the HP-97 executing the 67's -x- function when Print X is pressed, either in Run Mode or from a program step.

I haven't done Print Stack or Print Regs yet as it has been a chore just doing the -x-. The HP-97 microcode is complex and working along side it is somewhat hard.

The functions are enabled/disabled by the key code combination [f] [f] [c]
It is enabled when the C register = 1
It is disabled when the C register = 0

The new code will show up as 16 16 13 in program mode or when SST is held down, or if PGM as Text is enabled it will show as "Prin67"

This new program step will save to a card and will execute in a program. It will be ignored in an original HP-97.

I'll get to the others as time permits.

cheers

Tony
