No punch cards, but I did write the Windows version of ITSM (software accompanying the Brockwell and Davis Time Series book). The while thing was written in Fortran, the event loop and calls to the Windows API for UI and graphics. It's still the best damn visualization of a series + periodogram I've ever come across (if I do say so myself).
I can raise only one half of a hand as I started without punch cards, but we had cards at home because my mother "recycled" the unused one she add at the office to take notes.

Raise your hand if you first encountered Fortran in (eng) school and wrote your first Fortran programs on punch cards. (MTS for bonus).
