Version 1 Hardware pictures and diagrams

Most of the information here comes from Six's Guide to Ports website. and Jim Brain's website. I never bothered to take high-resolution pictures of any of my Version 1 boards nearly two years ago. I hacked my first Version 1 by looking at the information there. I'm trying to include most of the important stuff here too.

Highest resolution picture of the top (component side) I can find at the moment of the main PCB in an unmodified state. Sorry, I didn't take this one. Picture taken by Jim Brain.

Highest resolution picture of the bottom (where most of the hacking will be done) I can find at the moment of the main PCB in an unmodified state. Sorry, I didn't take this one. Picture taken by Jim Brain.

You should be able to use the information here, combined with the port pinouts on this page to attach your keyboard and disk drive. Keep in mind that the Ground on the two connectors needs to come from anywhere on the board where ground is available. I usually use the one designated for the power input from the batteries. Also the PS/2 keybaord jack requires +5V, which you will need to get from somewhere. (see below)

Powering your DTV - The DTV has a built-in voltage regulator that takes the batteries' 6V down to 3.3V for the system. However, a PS/2 keyboard is designed to run off of 5V and it needs to be exactly 5V regulated. So my suggestion is to find a 5V regulated power source to drive the entire thing.
