Williams D-12158 & D-12313 System 11 Backbox Interconnect Board

  

This PCB is a replacement Backbox Interconnect Board suitable for most Williams System 11B & 11C machines with part numbers D-12158-xxx and D-12313-xxxxx. The boards are supplied as a Complete Assembly, or, as a Kit with the IC Sockets and Fuse Clips already fitted. Also included are all the Header Connectors, Opto Isolator ICs, machine specific resistors and jumpers relevant to the Backbox selected.

Whilst each board uses different headers, a complete set is supplied to allow future proofing if the board is changed for a different machine. Please note:- Doing so will probably require different values and/or numbers of resistors and/or jumpers suitable for the'new' game. For D-12158-xxx machines, (Taxi & Swords of Fury), the relevant Headers, J4, J11 and J12, are common to the corresponding game sockets with misaligned fitting prevented by the Key pin. Pin 1 of J4 is Pin 1 of the corresponding socket and Pin 1 of J11 & J12 are marked on the board for which ever version is to be used.

For the self assembly Kit, sel ect the relevant machine from the drop down box and we will send all the parts required for that machine. For both the complete PCB and Kit, we will also include a parts location list to show where each component is fitted. Whilst every effort is made to ensure accuracy of the information supplied, the assembly of the board is at your own risk.

You are advised to exercise caution and to check and confirm the information and parts supplied are correct. No responsibility will be accepted for any damage to you or your game. It is not added by us.
