 I have come across a chip that I don't have the pinout of. It's a 4063, 
 presumably 4000-series CMOS. The one in the device is made by RCA.

 From the function in the circuit, I would guess
it's some kind of 4 bit   comparator. 

 Does anybody have the pinouts (16 pin DIL). It's not in any of my CMOS 
 databooks that I can find. If you do, could you please type them as a 
 simple text file (as in  
  It is indeed a 4-bit comparator.  Here is the pinout:

1	B3
2	IA<B
3	IA=B
4	IA>B
5	OA>B
6	OA=B
7	OA<B
8	gnd
9	B0
10	A0
11	B1
12	A1
13	A2
14	B2
15	A3
16	Vcc

   Good luck,
