I just loved his enthusiasm, as well as the ingenuity of using a length of wire as an acoustic delay line for storage purposes.

The opening shot was a bit of nostalgia as well, when he showed an Original-Odhner mechanical calculator, identical to the one one I have sitting on a bookcase as an example of the calculators we used at school around the turn of 1970.

Delay line memory goes back a lot further:

For us TV types, the use of acoustic delay lines is historically commonplace, though for analogue, not digital storage. From the 1 line delay in a PAL decoder to the massive 3.2ms (MILLI second) polygonal prism delays used in the BBC's world first 525<>625 standards converter.
