Is that AY-3-8192 or AY-3-8912?  If it's in a Vectrex it's over a year
old, and there's no AY-3-8192 in my 1982 General Instruments data book.
But there is an AY-3-8912 Programmable Sound Generator with the
following pinout:
		    __________
		   |    \/    |
Analog channel C  [| 1      28|]  DA0
	  Test 1  [| 2	    27|]  DA1
	VCC (+5)  [| 3      26|]  DA2
Analog channel B  [| 4	    25|]  DA3
Analog channel A  [| 5	    24|]  DA4
       VSS (gnd)  [| 6	    23|]  DA5
	    IOA7  [| 7	    22|]  DA6
	    IOA6  [| 8	    21|]  DA7
	    IOA5  [| 9      20|]  BC1
	    IOA4  [|10      19|]  BC2
	    IOA3  [|11	    18|]  BDIR
	    IOA2  [|12	    17|]  A8
	    IOA1  [|13	    16|]  RESET\
	    IOA0  [|14	    15|]  CLOCK
		   |__________|

Is this the same chip?  Or is there a newer one?
I'd include a detailed description of the chip, but it's pretty long.
