I never tried that, or even had this idea. But principally if you remove the original parts of a "Spice" calculator there should be space for the LP board somehow. The software could be adapted to the smaller LED display, which has only 11 digits. I know that the display principally is compatible, because it is also a common cathode 7-segment display. Also the keyboard is a 5*7 Matrix like in the "Woodstocks".

This way an HP-34C could be repaired and the unreliable solderless hardware could be replaced. But 26 wires have to be connected manually.
