RE: HP-65 more on the card reader
Hi all, regarding my HP65 mentioned earlier that seemed to have a definite preference for battery pack voltage, I think I fixed it. I replaced the capacitor (C3 ?) that was adjacent to the sense amp IC with a new 68uF axial tantalum. The unit now reads and writes under any condition without problems.
