Youtube video thing

I think it looks like a tribute to the IBM 7094 singing the song "Daisy Bell" in 1961. It can't be a commercial as it is too long.

Blue or black screen could be this: www.youtube.com/watch?v=-6hqmo7HhsI (Blue and black microphone on screen)

Moonbase alpha's text-to-speech was a popular meme a few years back. Now, I know you said that it didn't sing daisy bell, but it's possible you didn't watch to the end of this video because it shows up there. Soviet anthem plays around the 1:04 mark, and you remembering something about astronauts could be because that's what the game is based on. Also, the entire video is just a compilation of very short moonbase alpha singing clips. Doesn't hit on the "sounds from an old computer" part, though. Video is from 2014 which would hit on the seen it 2 years ago part. 

Oh my god I think you found it! I believe it's the first one. I can't listen to the audio atm but the comments talking about a whale song seems super familiar, along with the microphone background!

When I do get to listen to it and it doesn't seem to be the rught video, I'll let you know. Otherwise, thank you so much!
