Yes, the Apple Basic Color Display is compatible with both the HDI-45 connector and the DB15 RGB Video connector.
The Apple Basic Color Display has a mini-DB15 (VGA) to DB15 Connector attached to the end of the monitor's video cable. If you are attaching the monitor to the HDI-45 connector on the Power Macintosh, you need to use the HDI-45 to DB-15 cable to attach the monitor to the CPU.
