Hi Nate (and everything else),
if you want to take a look at the app, it is called "XMIT261". You can find it here:

It is the only source I found, for myself I made several backups, as I am not sure how long this is available at all. Although, this app is about 25 years old....
Hope this helps.
Best regards
Hans
