IBM 029 Card Punch and ASCII Machines

I recall back in the late 70s using an IBM 029 Card Punch to punch cards for
the DECSYSTEM-20.

 

As I understand it, the 029 was an EBCDIC machine, but of course the
DECSYSTEM-20 was ASCII.

 

Does that mean there was an ASCII version of the 029, or that there was
something in the card reader software on TOPS-20 that converted EBCDIC to
ASCII?

 

Regards
