Bob,

The source for TDFRMT, as well as the rest of OS/8 can be found here:
https://tangentsoft.com/pidp8i/file?name=src/os8/ock/CUSPS/TDFRMT.PA
https://tangentsoft.com/pidp8i/dir?ci=tip&name=src/os8

Several versions of the TD8E MAINDEC can be found here:
http://so-much-stuff.com/pdp8/software/maindec.php
Only one of them has a PDF, and I haven't checked to see if they fully 
match up with the binaries, but the starting addresses of the tests I'd 
been checking at least seem to match up with the DHTDAB.DG binary found 
here: www.pdp8.net/pdp8cgi/os8_html?act=dir;fn=images/os8/diagpack2.rk05
