33 * Nubus cards in Macintoshes are identified by 4 16-bit numbers:
34 * Category:	What is the main purpose of this card?
35 * Type:	Within this overall category, what kind of card?
36 * DrSW:	What software interface does it use?
37 * DrHW:	What specific hardware is it?
38 *
39 * For example, the "Toby Frame Buffer" display card is
40 *     Category 3 (display)
41 *     Type     1 (video)
42 *     DrSW     1 (Apple)
