Apparently I picked a bad-ish time to submit David Beazley's amazing talk about connecting his family’s 1978 Superboard 2 through a software modem connected to its audio I/O (all I/O was with cassette tapes), and hooking it up to a bunch of modern infrastructure. The talk is both impressive hacking, and also absolutely hilarious. http://news.ycombinator.com/item?id=2321602
