The B&C 810 is not a separate brand of disk drive, but a major upgrade of the original Atari 810, offered by the renowned American company B&C ComputerVisions (founded by Bruce Carmany). B&C became the "custodian of Atari's legacy" after the corporation itself began phasing out support for 8-bit systems. They bought up huge stocks of spare parts and began offering improved versions of the classic hardware.

These were original Atari 810 units that had undergone a complete overhaul: old capacitors were replaced, the mechanics were cleaned, and, most importantly, new control boards were installed. B&C often installed their own proprietary modifications, which addressed the 810's main problem—disk speed fluctuation. The units were often equipped with modified ROM chips that improved compatibility with contemporary versions of DOS (e.g., DOS 2.5). B&C were among the main distributors of the Happy 810 boards, which allowed the drive to read protected discs and operate faster.

If you see a B&C ComputerVisions sticker on an Atari 810 drive, it's a sign of quality. This means the device wasn't just "collecting dust in the attic", but was professionally serviced by a company that knew the Atari architecture down to the last transistor.
