I compiled this release with Microsoft Fortran for NT
Microsoft (R) FORTRAN PowerStation 32 for Windows NT (TM) Version 1.0
Copyright (c) Microsoft Corp 1984-1993. All rights reserved.
Included is the 1969 calendar (of course!), although you can change the year by editing snpcal.dat and re-running the program. This should build with f2c and other more 'modern-ish' Fortran Compilers.
I recommend printing it in landscape and setting a fixed console font at 8points.
