RE: Barcodes!

["Ian Lowe" <ian@xxxxxxx>]

The Hack is not reversible on the newer cats, as it involves
removing/lifting
pin11 on the Microprocessor, not something you can undo easily!

The -A Series cats could be hacked by just adding a bit of wire from +5V on
the cat to one of the input pins on the processor, but on the new 68-1965
design, this will short out 5v to 0.

Also, you don't need the original sofwtare. Mine went back in the box,
prior
to heading for the skip :)

Instead, download a copy of catnip 1.6 which reads the encrypted cat-scan
and
deposits it in just about any ap you want on your PC automatically.

Is the hack not easily reversible?

The main problem I see with is having to use the default software?
