HP65 card reader balls
I had a close call today. I dropped one of those clear 3mm diameter balls used inside the card reader to sense the card position. Luckily I have a daughter with eyes 30 years younger than mine and she actually found it!

But, it seems to me the chances of this happening again ( card reader *still* not working ) is pretty high. Does anyone know a good substitute for these guys? I was thinking of dollar shop beads or maybe nylon beads from a fishing shop.

Thanks.
Steve
