While an individual's experience may be typical, it is seldom exhaustive. We had a paper tape punch on our system well past 1977. I first used it in 1973 on a 370/155 but I know it was transferred from an older system and survived several CPU upgrades. The corresponding paper tape readers were attached to IBM 4PI systems that were installed on a fleet of aircraft. The readers were removed from the aircraft over an extended period sometime starting in 1984 after years of very infrequent use, if at all. I expect the punch remained available till the last reader was finally removed.
We finally gave up on the black paper tape and started using green Mylar tape which was borderline indestructible, though subject to crinkling. The used tape was saved for Christmas decorations. > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Edward Gould > Sent: Monday, January 16, 2017 6:12 PM > To: [email protected] > Subject: Re: Paper tape (was Re: Hidden Figures) > Gil: > That is not how I remember it at all.
