Use Lotus 1-2-3 to open the *.fm1 files. Also some spreadsheets programs can still open the .fm1 files, however the latest Microsoft Excel 2007/2010 no longer support that format. You can have luck with any earlier version of Excel, but you will probably loose some of the formatting from the *.fm1 files.
Possibly can be converted like any other spreadsheet documents.
