Not quite as visually compelling as the video, but pretty deep given their multi-decade history, is the BCS's Computer Conservation Society <http://www.computerconservationsociety.org/index.htm>. Unsurprisingly, it's got a heavy UK focus. It does occasionally dig into Canadian issues, partly because of the Canadian Ferranti-Packard company's design for the ICT (later ICL) 1900, arguably the UK's most successful mainframe.

Their journal, Resurrection, is very often an interesting read. The current issue, aside from big iron restoration efforts, covers the pre-history of the Raspberry Pi: http://www.cs.man.ac.uk/CCS/res/res69.htm

I'm kind of glad I missed out on the delay-line memory days. I just remember magnetic bubble memory, but only as it was fading out.
