MIDI decoding using 6402

[inman at interpath.com]

I am using a 6N139 to capture a MIDI message and a 6402
to decode it and must be missing something obvious.  
I am showing data on all but pin 12 (RBR1 of the 6402).  
At rest, the display shows pin 12 and pin 11 Low (RBR1
and RBR2), all other pins High.  During play, pin 11 
(RBR2) will go High, but at no time (even during sysex 
send, channel 2 play, high notes and low notes, pitch 
bend, etc...) will pin 12 go High.  Am I misunderstanding 
MIDI code?  Typically, bit 8 should be HIGH only during 
the status byte.  But it looks as if bit 8 of the MIDI 
character is appearing on pin 11 (RBR2) of the 6402 
because when I play a note, pin 11 blinks high for a moment.

Is the 6402 programmed for the wrong type of format?     

The 6N139 is wired as such:
	
1 NC 				6N139	8 +5
2 200ohm to  midi pin 4			7 
3 to midi pin 5				6 to 3K3 resistor to +5 
					  and to Pin 20 of 6402
4 NC					5 to grnd


The 6402 is wired as such:

1 to +5V	6402	40 NC
2 NC			39 NC
3 to grnd		38 to +5 High
4 to grnd Low		37 to +5 High
5 (RBR8) to LED		36 to grnd Low
6 (RBR7)to LED		35 to +5 High	
7 (RBR6) to LED		34 to +5 High
8 (RBR5) to LED		33 NC
9 (RBR4) to LED		32 NC
10 (RBR3) to LED	31 NC
11 (RBR2) to LED	30 NC
12 (RBR1) to LED	29 NC
13			28 NC	
14			27 NC
15			26 NC
16			25 NC
17 to clk 500KHZ	24 NC
18			23 NC
19			22 NC
20 from pin 6 6N139	21 to pulse 
			   (must be pulsed once after startup)	

Midi should be one start, one stop bit, no parity.  True?

According to the 6402 datasheet, connecting 37 and 38 to High
will program the chip to receive an 8 bit character.  34 loads
the program word and can be set to High.  36 sets the stop bit.
With 36 Low, the chip looks for one stop bit.  39 and 35 
control the parity check as follows with 35 for On/Off and 39 for
Odd/Even:

35	parity   39	type

H	NO	H	doesn't matter
H   	NO	L	doesn't matter
L	YES	H	EVEN
L	YES	L	ODD


I have tried the following:

-  rewiring pins 35-39 every which way for different words
-  replacing the 6402
-  different LED on pin 12, different wire for pin 12
-  moving the 6402 on the breadboard (bad connection?)

I have also checked pin 12 during MIDI send using a DVM.
It has no voltage swing at all.

I am getting the MIDI signal, minus one bit -- I think.
The 6402 datasheet says that if a character is less than 
8 bits, the justification is toward pin 12 (right justified).

If anyone has used the 6402 before, help would be 
greatly appreciated.
