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. cheers, Stewart
