I've never used AmiPro, but I could give it a try, or you could try it using wine maybe?

Here's the link: https://winworldpc.com/product/amipro/3x

Edit: Actually, this looks like just a demo. Sorry. But I have Lotus WordPro in a zip package, which is a later version of AmiPro, so maybe the WordPro can read AmiPro documents? Maybe? You could try. Here is the link for that: http://www.wzsn.net/xp/lwp.zip (Download size: 100 MB) This zip file contains the program called Lotus WordPro 9.7. To run, unzip the zip file's contents and then type: wine wordpro.exe and hope for the best...! :)

Edit: This program (Lotus WordPro 9.7) has an Import/Export feature, and it claims to be able to import AmiPro files. However, I downloaded a couple of sample AmiPro files, and it couldn't open them. So, I did something else. I downloaded https://lotusamipro.com/files/word2ami.zip and this converter is an addon for Microsoft Word. Using this addon, I was able to open the AmiPro SAM documents with Word without a problem!
