My dad had the Beta-1 Command Base (6970) and also a yellow astronaut minifig? They've all since been absorbed into the family lego collection.

I had a few myself as I was still playing Lego back then. What I liked most, after building the kit following the instructions, was to create my own mixing all the parts I had. I wonder how many hours I spend doing that :)

They should do remakes of some of these sets

I had almost all these sets as a kid!

Must have been nice growing up rich...

In my friend group there was only one who actually got one of those for Christmas (I think it must have been the Galaxy Explorer, I remember the cool cockpit and the specific moon baseplate).

For a time he was the star of afternoon play meetings, as no one else had something remotely comparable.
(I only had a box of basic second-hand Legos left over from the seventies).

For the rest of my friend circle those all were dreams while reading the mail order catalogues...
Nice nostalgic memories nonetheless! :-)

Back when Lego was simple and the only limit was your imagination. (Of which we had a lot back in 1980.)

I loved these so much.

I admit, these look pretty lame compared to the 90's Spyrius sets from my childhood.
