I started at Southern Bell Co-op student in '66 on a 33ASR writing Basic Programs on I think it was a GE635 at one of the Banks in Atlanta. There were eight holes but the 4th from left was the sprocket feed. If you put the tape in upside down it would saw it in two. https://en.wikipedia.org/wiki/Teletype_Model_33 One of my early adventures was converting the Long lines accounting tapes to punch cards on an 029. It was like cloak and dagger as to what pins did what. We couldn't show the IBM guy our manual and he couldn't show us his. After a couple of attempts cooler heads prevailed and the IBM guy says I'm going for coffee and left his 029 manual open to the pin-out diagram. When he came back the 029 was punching cards.

So every row on the tape could hold one 8-bit byte; I don't know what coding it was. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
