We had originally been using a laptop computer for boat navigation but with the addition of the Pactor modem for HF Radio email I wanted to switch to a dedicated 12 volt computer. I considered putting a system together from scratch but decided to purchase a small footprint DC system from Island Time PC’s.
The computer is 8″H x 8″D x 4″H and includes a DVD Burner, 6 USB Ports and 4 Serial RS-232 Ports. Since the PC is installed under the nav station I modified it so that I could remote the power on switch and LED and the disc drive activity LED.
