Scientific Word is now free for all

*Scientific Word* is now free. The code is identical to the former 
commercial version, but the activation process no longer requires a 
serial number and is therefore free.

All versions from 4.1 to 6.1 are available, but probably 5.5 and 6.1 are 
the only ones you need to consider. The open-source version of 6.1 
continues to be available but is now redundant.

Full details are on https://www.mackichan.com. Included are links to 
download the code and the manuals for versions 5.5 and 6.
