Yes a weak-bit :) Do you remember the time of floppy disk. A specific copy
protection was to read/write many time at the same address a 0 and a 1. After
some time when reading at this specific location you got either a 0 or a 1.
This was use as a copy-protection by some softwares. Amazinlgy Copywrite (a
nice copy tool at this time) was able to reproduce a weak-bit.

So somehow yes a weak-bit was smaller than a plain-bit :)

Should I add that this is plain OT !

Pascal.
