There are 3 versions at 
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/shsucdx.html
 
<https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/shsucdx.html>

Version 3.08 & 3.08a are the same, with just NLS updated. However, there is 
also 3.07 and 3.05.

You could try the middle one.
