Disabling HP65/67 card reader write protect

[Thomas Okken]

I finally had success with the cut card method as well. As recommended by Bob, I first cleaned the card I wanted to rewrite; I couldn't find my plastic erasers, but I made do by breathing on the card to get it slightly damp, then gently wiping it with soft cotton (i.e., T-shirt). I altered my cut card slightly: suspecting the angle of the cut was a bit too acute the first time, I cut off another sliver to get it closer to 45°.

I pushed the cut card in about halfway. The right point was easy to find, it's right where you start to feel resistance. Any less far and you get Error while writing, any farther and it won't be pushed out by the card being written, it just slides over. Which may be harmless but who knows.

It still took a couple of attempts, but I was able to restore my SD-15A in the end, so now I have a complete and functioning Standard Pac once again.

Thank you Don and Bob for your advice!
