I found a source (the Celestial WWW [now CelesTrak) for the infamous Spacetrack Report No. 3 (1.1 megabytes in PDF format), the NORAD report that defines the common mathematical models used to predict satellite orbits.

June 2, 1996
A minor ease-of-use improvement in the grid-square converter. The text input fields (especially the minutes and seconds fields of the latitude and longitude) were exact-size, which meant that if your browser defaults to insert mode in text fields, you could type your value and it would look right, but actually your value would have been appended to the default value, leading to confusing results. I made the fields a little wider so you can see when that happens.
May 31, 1996
Uh ... fixed another bug in the grid-square converter. The previous fix didn't work the *first* time you used it. I've had reports of problems with some Web browsers; if you are having any trouble now please let me know, and tell me which browser(s) you are using.
May 30, 1996
Fixed a bug in the grid-square converter. It wasn't handing South latitude or East longitude when converting lat/lon to gridsquare - it was folding everything into my quarter of the world. Thanks to Don Ferguson for point out the error.
May 27, 1996
As an exercise, I have cobbled together a Web-based grid-square converter. Please check it out and let me know what you think.
