The podcast, hosted by retro computing enthusiast Earl Evans, usually focuses on a single aspect or item from computing history. For example, the first podcast featured the Commodore Vic-20, and the latest (number 52) began a two part investigation into the 6502 Microprocessor. The podcasts have also included reports on vintage computing festivals, discussion of related technologies, and other such goodness.

I've personally only listened to the latest podcast, but I've subscribed to it via iTunes, and I'm looking forward to listening to some of the previous 'casts on the old Commodore computers.
