Just finished buying an HP 45 for parts but ended up restoring it. I will post pictures probably tomorrow of the dis-assembly, restoration and assembly, but I do have a question.?
What was HP thinking when it produced the HP 45 with an extremely inaccurate timing function?
Mine is 10 seconds slow per minute. I know I could calculate a correction factor to multiply the resulting times to correct for the tardiness but just what was the timing intended for? Okay thats two questions related!
PS I will be converting it to a quartz crystal for the fun of it and for an accurate timing circuit.
Cheers, Geoff
