The Friden Flexowriter, which used paper tape, preceded the IBM MCST and MTST. The US Senate used the Flexowriter so there might be an archive somewhere of paper tapes containing Senate documents. Here's a photo: http://www.retrotechnology.com/herbs_stuff/flex_recomp.jpg Both present the same problem of retrieval from obsolete media that's 40 years old. A recent survey by the Storage Networking Industry Association (SNIA) found that 80% of respondents needed to retain electronic records for 50 years or more.
