Sony introduced the world’s first portable CD player, the D-5 in late 1984. It was called a portable because of its size, not really because you could take it for a jog while you listened to your music. At first it was called the Sony Portable CD Player, the more popular “Discman” name came a little later. CD players took a fairly long time to catch on in the 1980’s because they were very expensive. Add to that the cost of early CD’s, which were about twice the price of LPs and cassette tapes. Sony’s first CD home player was more than $600. That made the Sony Portable CD D-5, which sold for about $300, a great way to add CD playing capability to your home audio system. Even though it was sold as a portable, it really wasn’t portable because it needed the included AC adaptor to work. You could listen to your CD’s via headphones, or get the docking accessory, which offered RCA stereo jacks for direct hook-up to your music system. If you wanted to actually take your portable CD player on the road, you needed the rather large battery pack accessory. I read that a set of batteries lasted for just about an hour on that first CD portable. And the D-5 was before the invention of CD-buffer, so you had to tiptoe to prevent skipping. That’s why it was more of a stay-at-home portable, than one you wanted to actually use on the go. I remember how much I liked the pop-up cover on this beauty. It had a see-thru window, so you could watch the CD spin. If you’re a fan of nostalgia, you can still find one on Ebay from time to time.
