To a point, sure.  But, for example, it takes file I/O traps and
provides its own implementation, backed by the host filesystem, rather
than letting the FreeDOS implementation talk to (presumably emulated)
disk hardware.

The point is to get the application running without the fancy hardware
(which is now EOLed) without having to rewrite the portions of the
application that talk to it.  The company has done an EOL buy of that
hardware, but that gives them only enough to last about half the time
we expect it to take to do the complete port/rewrite.
