Here are the two files in "zipped" format. Each file needs to be unzipped onto a separate floppy. Disk1.zip is the first disk and disk2.zip is the second disk for the Excel add-in PHstat version 1.2
After you unzip the files onto floppies, first thing you should do is read the Readme file from disk 1.
