Damn, that was pretty complete right off the bat. Sure you're not "retired", David?
The 1MHz podcast, although no longer updated, is enjoyable to listen to; I recommend going through them.
Another no-longer-updated podcast where the episodes are worth going through is One Man and his Mic: http://www.binaryzone.org/podcast/ It is about the various game music and composers throughout the 8-bit and 16-bit era, and it's funny to listen to and some of the compositions are mind-blowing (hearing what Tim Follin was able to do with a 1-bit ZX Spectrum speaker must be heard to be believed).
