Hi all,

i bought a HP 9100 A calculator and need some advice.

According to the owner, the power supply hummed and the backlighting
came one - nothing on the screen, though.

I think i should test the power supply and the tube first.

Any suggestions on where i could test voltages and what i should get?
How long would the screen take to light up?
If the calculator is stuck in a loop, would there be a display at all?

Would pulling the logic cards first be a good idea?


Thanks for advice,

Martin
