My first computer was a TI-99 ========:O
It wasn't mine as in MINE - it was just in the family. Chiefly I remember the space invaders and their noises. Well, that and its looks (generally not specifically - the brushed metally goodness - as I recall - juxtaposed with black plastic), which were beauteous for its time.
I see you can buy one on the nefarious ebay for a trifling amount. Now Hammer, who has moved away but was a pal* from the Lut (he taught kindergarten for a while, making him Hammer of the Tots), LOVED old technology. I used to show old 8mm and Super8 movies to my children (then make them make zoetropes) and Hammer would come in and sometimes bring old movies to show. He found a super ancient, 7 ton proto-laptop at a thriftshop once (when Value Village was on Sleater Kinney). All those things still work - they were made out of heavy plastic and metal, like you'd be keeping them for years and years. I bought an 8mm Bolex, complete with leather case and pristine, in a junk shop (the one by Black Lake) for $20 once, and gave it to Hammer - wow, was it ever a work of art. I used to buy every 8mm/Super8 related thing I saw, which was a huge amount (that finally I donated to the Film Ranch) including cameras, lights, editing equipment, projectors, films, and even a strange device to aid in transferring to videotape. Anyway, Hammer was an incredibly interesting and fun person and possibly** his house is full to the gills with ancient computers and wildly aethetically-pleasing movie cameras. What heaven!

*His mother is Mohawk and his dad's a jazz pianist - so he grew up in Las Vegas. I remember him showing me a book about Mingus, and saying, "Oh look - there's my dad."
