That is correct. There is no provision in the design of tpsDig to allow
input from a digitizing tablet. Marking landmarks on digital images has
many advantages. One of the most important is that one can correct an
error (such as digitizing a point in the wrong order) by just going back
to the image and moving a few points. With a digitizing tablet one has
to digitize all of the points again because it is unlikely that the
specimen can be placed in the exact same position that was used
originally. Note that tpsDig can also acquire images from TWAIN
compatible scanners. That may be a practical alternative for suitable
sized relatively flat specimens (such as large butterflies or leaves).

I am pretty sure the answer is "No".
I think the state-of-the-art is to generate an image from whatever you
are wanting to trace and use the image tools in tpsDig2.
FWIW. The DOS DS-DIGIT program (available from
life.bio.sunysb.edu/morph) used to support several popular digitizers
and might work today in a virtual machine, though the interface is
digitizer-specific. That program was written in Turbo Pascal that for
some reason did a CPU speed check at startup. Eventually, CPUs became
too fast for that built-in operation and the old DOS Pascal programs
began to fail. Years ago, I was able to run the programs by loading the
CPU with other tasks to slow them down enough for the programs to boot.
I no longer support these pascal programs, but get a kick out of
running
them sometimes in virtual machines. I had good success with the free
VirtualBox on Linux. It is worth it to me, though, to invest in a
commercial product. I used vmware workstation on Linux and, now,
Fusion,
on OS X. As for a DOS, I recall I successfully ran GRF-ND on FreeDOS
installed on a VirtualBox vm on Suse Linux last year.
