Depends on what options your 029 had installed (those function 
switches above the keyboard).  Some models allowed you to use them as 
an interpreter.  

A deadly-slow and noisy process, but better than nothing.  The 557 
could do, IIRC, something like 100 cpm, which was almost enough to 
endure the funky 60-column output.

What I don't recall is if the 029 interpret feature could work under 
control of a drum card.  You could simply interpret the sequence 
columns and get an 80-80 list on the 407, then later match them up.

The point of duping a deck was to add sequence numbers, no?  Stick 
your original deck in the 519 set up for sequence punching and then 
interpret the result.

That way, you didn't feel too bad when the cart carrying the trays 
that made up your Pride and Joy hit one of those filler strips in the 
raised floor and spilled them all over the place.

Cheers,
Chuck
