 ## Construction notes
 
-* J3 can be omitted if this controller is used with a FloppyEmu
-* All discrete logic ICs (except U15, the 74LS373) can be CMOS (74ACT, 74HCT).  As is unfortunately usual with the Apple ][, U15 must be LS due to timing issues.
-* if CMOS logic is used, then Q1/R6/R7 can be omitted -- the entire logic array can remain powered up at all times.  Connect pads 1 and 3 on the Q1 footprint.
+* The second floppy drive header (J3) can be omitted if this controller is used exclusively with a FloppyEmu.  Populate R11 and connect pins 1 and 2 on J7.
+* All discrete logic ICs (except U19, the 74LS245) should be CMOS (74ACT, 74HCT).  As is unfortunately usual with the Apple ][, U15 must be LS due to timing issues.
