Part of what seems to be QuickTime source code, ROMDefs.h which is "NuBus card ROM Definitions" appears to make STB references:

enum {

  displayVideoAppleGM          = 16843010L, /*Video with Apple parameters for GM card.*/
 +
...
 +
  drHwSTB3                      = 0x0002, /* Assigned by Kevin Mellander for STB-3 hardware. */
 +
  drHwSTB                      = drHwSTB3, /* (Both STB-3 and STB-4 share the same video hardware.) */
 +
...
 +
};
 +
</pre>
