Status

Finishing up board design. The above images are the current board layout overlaid on the (1) front of a Star Castle audio PCB and (2) back of a Star Castle audio PCB.

If all goes well with this board, I plan to modify it for a War of the Worlds Audio PCB.

Please contact me with any questions or comments.

Text below is in draft form and likely to be changed.

Overview

The Star Castle Reproduction Audio PCB is a drop-in replacement for the original audio PCB with most traces and components in the same locations as in the original board. The reproduction has the following upgrades over the original PCBs:

  1. Upgraded Resistors. All resistors are 1% tolerance (metal) rather than the 5% tolerance (carbon) used in the original boards, providing greater accuracy in the sound circuits.
  2. Socketed ICs. Sockets have been installed for all ICs for easier maintenance and troubleshooting.
  3. Component Labels. The reproduction board includes component values that were not labeled on the original boards.

Installation Overview

The Star Castle Reproduction Audio PCB is a drop-in replacement for the original audio PCB. Power off the machine and swap in the reproduction board. Attach the game's wiring harness to the board at (J1). This connector is keyed and should only connect in the proper orientation. The ribbon cable to the Cinematronics CPU (J2) is not keyed and it is possible to insert it backwards.
