not the actual cassette, nope. there's actually a .pdf here - unforunately, it looks like they de-bound a book and scanned it, so the pages are laid out a little wonkily. the relevant stuff starts on december 27, 1973 which is page #65 in both the book and the .pdf.

I'd up and buy the series if they had everything up through the cancellation.
yup ditto. especially if it included the american pilot.

Or Audrey/Laura precanon fem-slash, possibly.
you've seen the movie, right? it's already a prequal, might get in the way of your precanon plans...
