Seems the original must have been the XXDP TC11 DECtape formatter program 
by Robert J. Collins. I have no clue where I found the RT11 version of 
this, it must have been in 2005 after we got the TC11 and TU56 along with 
the 11/20 and other peripherals. The modified version was part of DECUS, 
it is listed in the August 1978 edition of the PDP11 DECUS catalog (page 
28, program no. 11-216), but apparently it isn't online (any more?).
