Apple AppleVision 850 - Manual (Page 14)

Connecting the monitor cable to various video connectors
To connect the monitor to a high-density port (45-pin port) instead of a
standard monitor port (15-pin port), you need to use an adapter. This adapter
is usually provided with your computer. If you don’t have one, you can
purchase an adapter (Apple part number 590-0337) from an Apple-authorized
dealer.
Other video connectors, such as PowerBook adapters, can also connect to
your monitor port with special adapters. For more information, see the
manual that came with your computer.
Note: If your Mac OS–based computer came with a VGA adapter for
connecting monitors, use it instead of the one shipped with your AppleVision
monitor.
