while we're on non-SW, off-topic preservation, i also have something to throw into the mix...i found an old tape I bought at a con of Batman material from the sixties TV show. old promos, convention footage, etc. it's been years since I watched it; i don't recall it being in super great quality, but I'm pretty sure I haven't seen any of it pop up on any filesharing (to the best of my knowledge).
there's gotta be a DVD worth of stuff on there, if anyone would be interested in doing the magic thing where the VHS becomes a DVD. i'd gladly send it off for transformation if this toots anyone's horn. lemme know.
