AVG Chip Replacement (137179-001)


Most of Atari's color vector games use a custom integrated circuit in the Analog Vector Generator (AVG) to handle memory addressing and stack functions. This chip (known as the "Address Controller" or the part number "137179-001") is no longer available as new replacement part from Atari or any distributors. Since these custom chips have been failing with increasing frequency over the years, I have produced a replacement to help keep those color vector games running.

The board pictured at left is simply plugged into the 40-pin AVG chip socket on a Space Duel, Star Wars, Empire Strikes Back, Major Havoc, Gravitar, Black Widow, or Quantum circuit board and functions as a 100% equivalent to the original chip.

In addition to being a functional replacement to the 137179-001 the circuit board includes two LED's that may be used to help trouble-shoot broken game boards by indicating some functions internal to the AVG operation.

The board is priced at $35 each.
