@@ -6,8 +6,14 @@ Each AY is connected to its 6522:
 * port A is connected to the AY's data pins;
 * bit 0 of port B is connected to the AY's BC1;
 * bit 1 of port B is connected to the AY's BDIR;
-* bit 2 of port B is connected to the AY's BC2; and
-* the AY's reset is active if all of bits 0, 1 and 2 are reset.
+* BC2 is connected to +5v; and
+* bit 2 of port B is connected to the AY's reset.
+
+So, logically:
+* BC1 is active if bit 0 is set;
+* BDIR is active if bit 1 is set;
+* BC2 is always active;
+* reset will occur if bit 2 is reset.
 
 The three channels from each AY are mixed together with equal volume.
