48 * Quadra sense codes taken from Apple Technical Note HW26:
49 * "Macintosh Quadra Built-In Video". The sense codes and
50 * extended sense codes have different meanings:
52 * Sense:
60 * Extended Sense:
61 * bit 2: pins 4-10
62 * bit 1: pins 10-7
63 * bit 0: pins 7-4
68 * Reads from the sense register appear to be active low, i.e. a 1 indicates
71 * Writes to the sense register appear to activate pulldowns i.e. a 1 enables
75 * determine if extended sense is to be used, and then check which pins are
