Re: Battery replacement HP75C Message #2 Posted by Sylvain Cote on 5 Aug 2013, 11:02 a.m., in response to message #1 by Chris H (UK)
Hello Chris,
From my perspective you should keep it and replace the dead NiCd AA cells.
You can find more battery information
here,
here,
here
and here
Now if you want to play with it, I suggest that you connect your HP-75C to HP-IL devices (printer, storage, video, etc).
The least costly would be the to connect the 75 to a PC with the following setup:
a) PIL-Box (HP-IL to USB box from Jean-François Garnier, here)
b) HP-IL cable (needed between the HP-75C and the PIL-Box)
c) USB cable (needed between the PC and the PIL-Box)
d) HP-IL devices simulators (here and here)
