What is inside a dongle?
« on: November 14, 2015, 09:33:08 AM »
Found this old dongle lying around at work, from some software that is both no longer in use, no longer supported and where there was issues with the supplier not paying a license fee to the developer.

Inside the parallel port feedthrough is the following 2 sided board, containing the single 20 pin DIP on the one side, and the tiny Atmel microprocessor on the other side containing the "secret" code sent in via the parallel port status pins.
