Worked on an IRIG-B Decoder

Manitoba Hydro wanted an IRIG-B decoder unit.  It would listen to modulated IRIG-B, decode the time, and provide details of the time on a serial port.  Filipe Fernandes and I did the system architecture.  Filipe designed the board, based on a Motorola MC68HC11 development kit, and did the programming in assembly language.

The project was a success, but he was moved off to another project just as it was finishing, so I completed the programming.  The design was a success.

This was my first exposure to IRIG-B, and I was fascinated.
