What memories of acetate tape ...... I lived near the Lockheed Skunk Works in Burbank ca and would buy a skid of 1/2" Univac 10" acetate brown odixe computer tape at salvage for 25¢ a roll. Had a slitting jig and turned out 1/4" 1.5 mil 7" tapes for all my friends and local discount store.
For the era it sounded better than the black oxide paper backed 3M which was the bargain tape in those days.
Come to think of it i still have some of both in my archive. The stuff recorded great on my Magnicord PT6, which i still have.
This list sure has a lot of history that makes for interesting reading and research. Keep it up.
