The paper tape reader for the SCM Typetronic 2816 could read a form of edge-punched
card but presumably these weren't compatible with anything else apart from the ones
it produced with its own 'Vertipunch' unit.
See page 22 of the operator handbook:

I do have this tape/EPC reader (no cards unfortunately) and can take some pics if
anyone's interested.
