Q:  Does DOS have some sort of maximum file size limitation?

A:  The only limitation on the size of a file is the size of the
partition on which it resides.

For example, I just made a 70MB partition on my 3Server3 and was able to
create a 68MB file there (2MB was already used by the system
software).

I performed the above experiment by creating a sector
size of 2048 bytes and a cluster size of 4 sectors, an 8KB
clustor.  I then created a file that was 16 bytes long on that
partition.  A DOS DIR command showed the file as 16 bytes long,
but a comparison of the total available bytes before and after
the file was created showed a difference of 8192 bytes (8KB).
Confirmation of what we all we thought all along - funny
partitions use up a lot of disk space for small files.
