I am trying to locate a serial lock/key for my old Tango PCB v2.11a software package. It is a printed circuit board design software package, DOS based. I have a lot of designs using this software application and have lost the serial lock/key.
Does anybody know where I can purchase one of these keys? ...or know of another application that can read these files? ...or know the file format so that I can create my own viewer?
Thanks. Any help would be appreciated.
