Looking back at an old Ham radio from October 1974 there is an ad in there from Joe DIckens WA9UGE in Urbana, Il. offereing RTTY Picture Perf Tapes, 5 level 11/16 tape from 3 min to 7 hours in length. I'm don't remember if i worked Joe or not back then but wonder if anyone remembers him or if he is still around. Guess i could check QRZ.com, duh! Larry W0OGH
