I think I just peed a little bit. I love the classic 70s & 80s space sets - even some of the early 90s stuff was pretty cool.

If you're wanting to restore the set to its original glory, you can probably pick up the parts you need on Bricklink (www.bricklink.com). Some of the older grey parts (they changed the colour formula a few years ago) are hard to come by now, (that TV Antenna piece is pretty rare to find in good shape), the same with some of the translucent yellow as well.
