There are several ports of Borland's Turbo Vision on the Internet:
This page contains the source of the tvision port as distributed by FreeBSD.
The FreeBSD port is based on Sergio Sigala's TVision + parts from stl-tvision + Additional patches by
Max Khon to support FreeBSD 5.x + misc. patches contributed by Erling Jacobsen in PR 71544 (Erling's patches can be downloaded from here).
Since the patchset against the original tvision grew quite large, i uploaded a patched tarball to this site.
