HP-65 Card Reader Problem Help

[Geoff Quickfall]

Try adjusting the height of the pinch roller by rotating it through 180 degrees using the slot in the pinch roller axle.

I fastened a 'screw driver' for the slot by bending a stiff metal arm from a pair of tweezers. This so the adjustment can be made while the pinch roller is in situ. Adjust the axle by a few degrees, then test a write then read. Adjust again and test, again and test. Once through 180 degrees you are repeating the height cycle. I test through the next 180 degrees just in case I missed the sweet spot.

I did not post the wiring pics as Etienne beat me to it. Comment somme vous Etienne?
