[Coco] Removing the tape to make a floppy write protected was not an effective physical block after all

[John Guin]

Today I learned:  https://scarybeastsecurity.blogspot.com/2020/06/a-wild-bug-1970s-intel-8271-disc-chip.html

The author doesn't definitively find the culprit but makes some good guesses to the source of the corruption.

Fun reading for a small set of folks.

Enjoy!
