In the 1970's, a friend of mine's dad worked at NARF (Naval Air Rework Facility) Alameda. They made system backups on paper tape, because it was immune to EMP effects.

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. I started keeping IBM sales manual pages that were "discard this page" when updates came out in about the 1970 time frame. I realized that I was throwing out history, so I kept some that I thought were important. Also I hung on to old IBM Blue Letters as product announcements were called. When I moved last summer, I shipped about a 6" tall stack of them to the Computer History Museum in Mountain View, CA. http://en.wikipedia.org/wiki/Computer_History_Museum Jim Mike Walter wrote: > And just this morning I had been wondering about those who have > contributed to this thread, wondering how they could remember so much > detail (even if some memory had a few parity checks).
