HP-19C not yet repaired!

After having two successfully running HP-19Cs I still have my hopelessly corroded third calculator (actually this third calculator was the first I bought). I do not want yet give up to repair this underwater HP-19C. When I removed all components from the power supply/printer board last week, I did not really had in mind to reassemble them, but now I did. I ordered new components and completed the work today.

With new components assembled. All labeled components and resistors are new, they can be bought from todays electronic providers, even the flat ribbon connector.

The functional test is not yet performed. I will insert this board into one of my working HP-19C and see if it prints? Give me thumbs up please! Smile

That's one small step for a man - one giant leap for mankind.
