Brings me back to my childhood!

I remember this back in the day....came with my lego set, a small cargo ship.

6950 was my absolute favorite!

Hmm, I had one very similar to 897

Thats a cool kit too, I so want them to rerelease these!

I have 6823, 6870, and 6929, I think. Plus both sets of baseplates.

Seeing these ads, I'm surprised at how old these models were. They had been out for quite a while before my parents bought them for me.

My brother had 928 and it was glorious

I'm pretty sure I had every one of the space sets you've posted, and many more. I had a large Rubbermaid bin, probably 2' x 4' x 2' deep that was tricky to close the lid it was so full and they almost exclusively space sets and the black space sets.

I had 928 too, never could forget the front windshield angle brick w/ the giant space logo on it :)

Same here, it was the only toy I could manipulate my dad into buying as he was an engineer.
