Wow, Chuck, that is fascinating info that I had no idea was so easily
accessed. Thank you! It looks like the tape production in the 80's was 30M
to 40M reels per year so my guess at 100M was high but not too far off.
I super like some of the product codes just on those pages. E.g. 35711 22 is
Analog Computers, and 35751 75 is Teleprinters under 20 characters per
second (e.g. Model 33's which saw a steep decline through the 1980's. I'm
guessing they would've peaked in the early 70's.).
