No, the IBM 2671 paper tape device was a reader only. The paper tape
punches were from older systems. I guess paper tape got punched on
teletype machines in S/360 days. I had a customer with a 2671.

There was an emulator for 360/30 and 360/40 (DOS/26) we also ran 1401
programs on a 370
Just thought this might interest those who remember the 1401. :-)
