Dave the TA11 (DEC proprietary Phillps Cassettes) were 150 ft long. I
just looked in my 1976 Peripherals Handbook -- Tape capacity of 92,000
bytes (not kbytes mind you). Two tapes per TA11; one for the OS and the
other the user. We had a couple at CMU on 11/20's running RT-11 in the EE
Digital lab for the RT system's course - in fact, the famous "110v
non-maskable interrupt" occurred on one of those machines

32MB really was ginormous back in the day; our
labs had RT on RK05's,
which held about 2.5MB. Way more than a DECtape.
When I started out, I had it on RL01s. But I suspect you have a few
years on me. ;) That was quite a bit of space at the time.
