You can "try-before-you-buy", its shareware!  Definitely worth the 50 bucks
they want from you to register, but its legal to try out first (for about
30 days, I think.)

ftp over to site:  wuarchive.wustl.edu

and then:

cd  /mirrors/msdos/sysutl       <----- changes to appropriate directory
type binary                     <----- sets transfer mode to binary files
recv  4dos22.arc                <----- get the archived 4DOS system & docs
recv  4dostip.arc               <----- handy start-up tips, also archived.

On your pc, most of the "ARC"-type programs should work to unarchive it:
PKXARC, ARCE, etc.

Good Luck!
