AP also recently added Space: 1999 [Season 1 of 2].
I remember watching most of that series, but I missed the final episodes — no VCR/DVR in those days.
I watched the first two episodes last evening on AP. They weren’t too dated [1975-78], except for the bell-bottom slacks. The graphics were okay, too. The series has been remastered for widescreen.
Each season has 24 episodes of about 50 minutes in length with an episode 25 added to Season 2 in 1999.

The Eagles were the best part of 1999.
