HP-19C Repair Odysee

[Jonas Sandstedt]

Hello,

Regarding printheads for HP-19c and HP-97, when I measured my HP-19c printhead the resistance was about 14 ohms for each resistor. When reading Sharp manuals, such as

https://sharppocketcomputers.com/4HK7JnF...manual.pdf

it seems as if the Sharp printheads have about the same resistance (see page 10).
Sharp also has a small flexcable that runs into a connector (see 26th page).
I guess the same may be the case for the Sharp printer CE-126P and calculator EL-550, as well as other similar calculators with thermal printers such as Panasonic, Texas and Canon of the early 1980's. Has anyone tried to use such a non-HP calculator or printer as a printhead donor for HP-19c or HP-97? There might be technical aspects that I have overlooked, it would anyway be interesting to know if it could be even remotely possible, since that could open for new replacement opportunities.

best regards
Jonas
