PORT 2 is an 8HP, 37mm retro joystick adapter.

Current draw V+ 80MA / V- 50MA

Gate outputs are +5v

Paddle cv outputs can be set to unipolar or bipolar.
Paddle pair fire buttons are routed to joystick L / R gates.
Unipolar - 0 to +5v
Bipolar - -5v to +v5

Module can be used with a single stick, two sticks, four paddles or a stick and a pair of paddles.

The module consists of two dsub joystick ports which are compatible with all the old joysticks from back in the 80s/90s retro days of C64, Atari, ZX Spectrum, STs and Amigas.....

These joysticks consist of four on/off gates on the X/Y axis of the stick and a fifth gate on the fire button. Examples of compatible sticks are the competition pro, Atari joystick, Zip stick, quickshot 2 and the Cheetah 125+. There are numerous others. A search of retro joysticks will yield plenty of results.

The module is also compatible with the paddles that would come with an Atari 2600 system. The paddles require a simple mod that involves soldering a single wire into them to work properly with the module. No extra parts or desoldering is required. It's just one wire and a couple of minutes with a soldering iron.

****************************

NOTE: This module will NOT work with things like Sega megadrive/master system or Nintendo controllers. These use multiple fire buttons and rely on some cpu decoding to work properly.

****************************

Initial tests reveal this module to be an absolute killer in a noise/powerelectronix rig with a joystick/paddle pair combo for gate/cv control over a noise generating configuration. I'm sure it has plenty of other uses, but the SFX / noise rig is where it's at for me when using things like this.
