PRD-650

The PRD-650 extended the Discman idea into portable CD-ROM use as both an external drive for early laptops and a standalone audio CD player, combining a detachable battery pack with a more utilitarian body than the music-focused players around it. It is less about listening culture than about making the compact disc itself useful in more than one context.

That dual role is really what defines it. The PRD-650 is part of the brief overlap where personal audio and personal computing still had not fully separated in hardware terms, and the optical disc itself is still being treated as the flexible center of both worlds. It feels transitional now, but in a revealing way.
