this? Some of the Sol tapes I've looked at are way too corrupted for such
a simple technique to work.
There are a lot of communication theory ideas that could be applied to the
problem directly; in addition, the file format is going to have some known
structure that could be used to help train the receiver and disambiguate
some cases.
I'd be interested to hear more.
Me too. This is what vintage computer preservation is all about. Dwight
has always been one on the leading edge when it comes to this.
