Not a link, but a video. A computer from 1959 (IBM 1401) at the Computer History Museum, compiling FORTRAN.

The Youtube user has a lot of good material on restoring historical hardware.

Also, be sure to read the email thread linked in the video comments. It's a conversation between the restoration team and the compiler's original authors (now in their 90s).

If you're in SF and you want to see the 1401 in action, the Computer History Museum used to show it to the public on Wednesdays and Saturdays. Hopefully those demos will resume once the coronavirus situation's resolved.
