My Take

This is one of a series of high quality breakout boards produced by Dorktronic and distributed on Ebay. These are all new, he has designed them and soldered them together himself. The product is the breakout board only. The breadboard shown in the topmost picture to the right is just to show how it fits in, but is not included.

This is a joystick port breakout board. It has a female DB9 port, designed to be plugged into the controller port of a Commodore 8-Bit computer. It can also be used for other platforms that use the same basic pin arrangement. Atari being the most obvious, which shares all of the same pins as a C64 controller port, including the PotY and PotX lines. The lines are listed below.

See: Atari 2600 Joystick Pinout

Each of the 9 lines from the joystick port are connected to downward facing pins that are aligned to fit the holes of a standard bread board, which can be fit beneath the breakout board. The pins of the breakout board are split and laid out so it can be mounted such that the 5 digital and 2 analog signal pins connect to 7 parallel rows in the middle. While the VCC and GND pins align to connect to the bread board's power and ground outside rails. You can see this in the topmost picture in the sidebar.

Pin Arrangement

Each of the pins is labeled both by number and by its function according to the way the standard joystick uses them.

Pin # Function
1 Up
2 Down
3 Left
4 Right
5 Pot Y
6 Fire
7 +5 VDC
8 Ground
9 Pot X

The board is ideally suited to prototype anything which is designed to interface with the joystick port.
