Another old CAD program is NEC2, the antenna (etc.) simulator.  Derivatives of it are still around.  About 20 years ago I found a version (in FORTRAN IV) which had been tweaked for DEC Fortran, and worked fine with gfortran.  I found that the documentation and full source code were available from the US Government (in printed form).
