Laptop Navigation

This has been a pet project. And I have amused myself by persisting in making all these old and outdated products work satisfactoraly together.

Issues:

1. C-Map charts require screen resolution of 256 colours. Therefore used an older Laptop running Windows 98 with screen colours set to 256.

2. Garmin GPS-60 is available with a cable interface to the GPS but requires the interface (cigarette plug) to power and (DB9 serial plug) for data to laptop

After some research the required pin assignments for the plugs was sorted out and plugs made. - Wiring diagrams for power and data included in the images.

In Pekeri I have installed a couple of cigarette plugs for power. One for the GPS and the other for the inverter to charge the laptop. I also use these plugs to charge my mobile phone when necessary.
