This parallels the situation with The Smart and Friendly, where 2.47 (2080) and 1.40 (4080) are combined - note also the same relationship between the numbers.

If you open the firmware with any text editor, be very careful not to alter it... the consequences could be disastrous, so copy it first.

Use any popular FTP search to locate the file pfe101i.zip - This is version 1.01 (Win32), the final version which supersedes the older 7.02 development stream. A windows 3.1 version is also available, file pfe101.zip
If you have difficulty finding these, I am prepared to put local copies on my site, or find some current accessible archives.
One good place to access FTP and other searches is the DOGPILE search engine.
