The author of DTA, David K. Mason wrote a book called "Morphing on your
PC," which included two 3-1/2" disks. On the disks were a few utilities
(DTA, DMorf, PolyRay, and a few others). The book had significant
information and is well worth the price. I just checked and Amazon.com has
it listed as available.
