Know that :-) We had Ampexes on-air, and RCAs in the editing suites. Those
were really lovely machines. All moving parts were controlled by pneumatic
actuators, it was phssst, pfff, pssssst all the time while editing. Below
the actual tape deck there was something like a cubic meter of electronics.
For slow motion playback (mainly used for soccer) there was an analog hard
disk recorder. The disk was around 40cm diameter and the whole thing was
packaged in a glass case, you could see the heads moving.

It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
