I want to present you a small HP-19C repair story here in the forum, which I and a friend had experienced recently. I have provided it as .pdf file with images for download.

I hope you enjoy the text while reading. In any case we had a lot of fun at "one of the best birthday workshops ever".

Hi! Congrastulations for your great work!
I'm with a deffective 19C here too and your article is being ot great help in my work! Thanks!
I was reading all comments in the thread, but they go away to other topics and I would like to go one step back and ask:
You said:"After removing the printer from the circuit and simulating the ON/OFF switch, MAN/TRACE/NORM and the home switch" -well, I did the connections for ON state: connecting S1c – S1d – S1e (12-9-2) togheter. But, what to do with HOME and MAN/TRACE/NORM? Could them be left open just for simple tests?
Best regards
Artur
