Just as most of the others have said, I'm into the retro computers that I had when I was growing up. My first computer was a TRS-80 Coco 1 which I learned to program on. A few years later I got into Apple IIs and then eventually the Amiga 500. I had loaner PCs that I did work programming on in those days but I'm not nostalgic about those DOS boxes one bit.
My collection consists a few Amigas, an Apple IIc and my original Atari 2600. I'm actually glad I kept a lot of my original machines all these years. There were many times that I almost ditched them. My originals are the ones I care about the most. The stuff I bought in recent years don't hold as much value to me.
