RE: HP-19C Printer
Very interesting Tony,
I do not think I can offer any more help other than checking for voltages on the connector pins between the boards that I am sure you have already done. If you could have access to a working HP-19C, you could of course test the upper part of the calculator (logic board, keyboard, display) in a known good PSU/printer board to quickly find out in which part the malfunctions lies. That is of course not easy since it is a relatively rare calculator. best regards Jonas |
