Vintage Sony D-50 Portable CD Player & AC-D50 Adaptor first Sony Discman RARE

Vintage Sony D-50 Portable CD Player & AC-D50 Adaptor first Sony Discman RARE. Sent with Australia Post Pre-Paid Parcel Post Satchel 500g. In excellent working condition! The first discman Sony ever released! The D-50 was the first portable compact disc player. Released only shortly after the compact disc system was introduced, it represented a major technical achievement, and was of course the worlds smallest compact disc player at launch. Much folklore surrounds the development of the D-50. It is said, for example, that the design brief stated that the total size should be no bigger than three (or four, depending on who you believe) compact disc cases stacked on top of each other. If this was true, the designers certainly got close to this goal. It is also said that the D-50 was offered at a particularly economical price to help popularise the compact disc format. This may also be true, but though it was cheaper than the CDP-101 (Sonys first domestic compact disc player), it was still pretty expensive, especially for something fragile that gets taken outside. The complexity of the D-50 makes any attempt at a description of its inner working impractical, one could fill a whole website with the details of this one model alone. However, it should not go unrecorded that many special techniques and special components had to be employed to condense a functioning compact disc player into the small casing, which does not look excessively large even now. In particular, the special (and highly complex) integrated circuits needed to decode the digital data from the disc were not at this time available in formats intended for battery portables, so special alternatives had to be developed. At the time, the error correction chip of a compact disc player was the most complicated object to be found in the home. Imagine the task of miniaturising it!
