The hyphen preceding a signal name indicates that the signal is low. Note
that 8-bit devices that connect to the P-cable leave these signals open:
-DB(12), -DB(13), -DB(14), -DB(15), -DB(P1), -DB(8), -DB(9), -DB(10), -DB(11),
+DB(12), +DB(13), +DB(14), +DB(15), +DB(P1), +DB(8), +DB(9), +DB(10),
+DB(11). All other signals are connected as shown in Table 4-3.
