        FWIW  You could get MS-DOS versions 1.25,
2.1(something) and 3.1 for
 the Zenith Z-100.  There's also a guy out there that wrote a program to
 patch PC-DOS 4.0 to run on the Z-100. 
Is there a 3.31 available for it? 
     Not that I know of.   MS-DOS 3.1 was the highest version that Zenith
released for it. The PC-DOs 4 is a private effort by John Beyers

 MS-DOS 1.25 is basically the same as PC-DOS 1.10
MS-DOS 2.11 is similar to PC-DOS 2.10, but is the most commonly customized
for alternate hardware version.
