Product Description
Note: photos below is the V2 unit. The 2026 interface does the same plus more

The original purpose of this interface was to support the expansion controllers of the Intellivision and Colecovision consoles. Why stop there! This interface supports as many 9 pin controllers and paddles as possible!

This page focuses on the Intellivision and Colecovision but enjoy any of the supported controllers!

The only way to play Intellivision and Colecovision games is with their unique and original controllers using the real hardware produced in the 80's. The second option would be in emulation on the PC but the PC keyboard has no way to reproduce the Intellivision 16 direction disc, the Coleco rollerball, or the feel of the controllers.

Enter the Ultimate PC Interface. It allows you to connect two (2) controllers with the PC through a USB connector. The controllers can be a combination of any supported controller.

What makes this the Ultimate PC Interface? It supports the Intellivision ECS keyboard and Piano! Play the ECS games as they were meant to be played. Learn to type 80's style with Flintstones Keyboard Fun. Melody Blaster must be enjoyed with the Music Sythesizer.... and now on your PC. Ultimate PC Interface is the only interface that supports both ECS interfaces!
You will need 9pin extensions to be able to connect to the 2026 Ultimate Interface

And there is more! Support for the Colecovision, Coleco Rollerball, Coleco Driving Wheel, Coleco Super Action controller, Atari 2600, and Atari 7800 Proline controllers! (see emulator support section below) Even though there are two connections to one interface, you can still mix and match controller types. A majority of controller buttons are mapped the same making it easy to define one controller type in an emulator and then change controllers without having to redefine it.

Wait! And there is even more! Support for the Atari 2600 Driving, TI-99, Sega Master System, Fairchild Channel F, Magnavox Odyssey 2, and Sega Genesis 3/6 controllers is also included.....

... and more!!! If you have a 2014 Intellivion or Colecovision Flashback controller and want to play more games, there is also support for those controllers! (See emulator support section below.)

• Supports the Intellivision Music Synthesizer. Currently only supported by the jzIntv emulator
• Supports the Colecovision spinner which is used by the Super Action Controller, the Steering Wheel, and the RollerBall through the emulator's mouse and joystick support. (see emulator support section below)
• USB 2.0 and backwards compatible with USB 1.1
• Compatible with Windows/Mac/Linux - any O/S that natively supports USB HID devices
• Data transmitted 1000 times a second for minimal delay

Emulator Support

The Ultimate PC Interface is 100% supported by the Intellivision jzIntv emulator (Available HERE), the Colecovision CoolCV emulator (Available HERE) and all other emulators that supports USB devices as the interface presents itself to the operating system as a joystick. The Intv ECS keyboard and Intv Music Sythesizer modes may not be properly recognized by all emulators. An example would be Nostalgia where it does recognize the ECS keyboard but Nostalgia uses the computer's ESCape key to exit a game so Flintstones Keyboard Fun will not be playable.

Using the Ultimate Interface

The interface unit has 4 modes. Use the switches to change the mode. See the interface label for reference. The side with the label is considered the TOP / UP side.

• Auto Sense Mode - left switch UP, right switch UP
- for ALL controllers excluding the controllers listed below

• Amiga Mouse - left switch DOWN, right switch UP

• Atari ST Mouse - left switch UP, right switch DOWN

• Atari CX22/CX80 Trackball - left switch DOWN, right switch DOWN

NOTE: The switches can be changed while the USB is plugged in. After making the changes, press the black button on the other side. There is no need to hold any mouse/trackball button. Switches affect jack/controller B/2 only.

Using the Autosense Mode

Autosense Mode supports all supported controllers.

The GENERAL RULE for all controllers is to hold first option below that applies while triggering AutoSense:
• Gamepad "A"
• Keypad "0"
• Button #1 (top/left)

The default mode (if no buttons are pressed when pluggin in the unit) remembers the last controller last recognized.

To have the interface recognize a controller listed below
• press and hold the required controller key/button
• press (& release) the black button
• release the controller button and enjoy!

Autosense for specific controllers

• Amiga/Commodore controller, press fire button or button #1 on 2 button controllers.

• Atari 2600 Paddles - hold paddle #1 button

• Atari 2800/Sears Video Arcade II - hold either side button, knob towards center

• CBS Booster Grip - hold grip switch

• Coleco Rollerball: the switch should be set to Rollerball (not Joystick)

• Coleco Steering Wheel: connect a Coleco controller and press zero. Connect the steering after the controller is recognized.

• Fairchild Channel F - push down

• All Famicon, NES, and SNES - hold A+B for button A/B X/Y swap

• FM Towns Marty - press shoulder button

• Gemini Dual Command - knob towards center

• Intellivision ECS Keyboard - only on power up, hold the "0" key

• Intellivision ECS Piano - only on power up, hold the left or right most end key

• MSX and X68000 controller, press fire button or button #1 on 2 button controllers.

• TI-99 controller, press button #1. Only one controller in port A is recognized. Port B will not work with TI-99 joystick.

AutoSense special notes

•Analog controls (2600 paddles, 2800/SVAII knob, Bally Astrocade knob) turned full right can cause the controller to be miss-detected. Turn towards center.

•Atari 2600 Driving may be miss-detected - use joystick or paddles for AutoSense, then change to driving

•Trak-ball/mouse can only be used in jack B. Set switches, then trigger AutoSense by power up (VERSION 2) or press black button (VERSION 3)

•The Atari 2600 paddles are part of a "2600-daptor" mode. When in this mode, you can freely switch between 2600 paddles, joystick, and driving just like you can with a 2600-daptor - no need to use AutoSense. You can also AutoSense into this mode with 2600 joystick pressed right. AutoSensing with the 2600 joystick fire button will actually select Sega Master System mode, but this works just fine with the 2600 joystick & driving (but not paddles).

•To activate the joystick mode for the Coleco Rollerball and Steering Wheel, hold ONLY the asterick (*) key on both controllers.
What is mouse and joystick mode? There are no emulators that natively support the Colecovision spinner. Emulators will interpret the PC mouse input as the rollerball/spinner. The interface interprets the Coleco Rollerball and Steering wheel as a mouse allowing them to work in these emulators. Some emulators do not have mouse support or you may want to use the rollerball as a joystick. You need to have the joystick version of the games when in this mode. (Example: Turbo and Slither standard controller versions)

Special Keys

The Intellivision and Colecovision controllers support 3 additional keys. To activate them, press two keys at the same time.

With the Intellivision controllers, holding down the 4 and the CLEAR buttons on the controllers, the interfaces returns to the emulator button 4. Holding down the 5 and the ZERO buttons on the controllers, the interfaces returns to the emulator button 5. Holding down the 6 and the ENTER buttons on the controllers, the interfaces returns to the emulator button 6. With the jzIntv configuration below, the emulator will PAUSE, RESET, or EXIT.

With the Colecovision controllers, holding down the 4 and the right fire buttons on the controllers, the interfaces returns to the emulator button 7. Holding down the 5 and the right fire buttons on the controllers, the interfaces returns to the emulator button 5. Holding down the 6 and the right fire buttons on the controllers, the interfaces returns to the emulator button 6. With the CoolCV configuration below, the emulator will FAST DISK, RESET, or EXIT.

For the Sega Genesis, MODE + any other button (A, B, C, X, Y, Z, START) activates PC joystick buttons 9 & up.

Important Connection information

The two DB9 connectors on the interface are labeled with one or two boxes (player 1 and 2) In the picture below, the "A" and "B" would be your extension cords. "A" connects to player 1 side and "B" to player 2 side.

How to configure Intellivision's jzIntv

The jzIntv emulator supports mapping the controllers, PC keyboard, and Music Sythesizer. This is accomplished by using a "hackfile". To use the hackfile, you need to append the switch "--kbdhackfile" to the command line. An example is:

jzIntv --kbdhackfile=C:\jzIntv\hackfile.cfg c:\jzIntv\roms\demo.bin

jzIntv supports multiple input configurations, F5, F6, and F7. F5 is the default mapping and F7 is used for the ECS keyboard.
F6 (map 1) will be used for the Music Sythesizer.

You may either use this HACKFILE.CFG which contains comments or you may configure your own hackfile using the settings below. If you have not upgraded your unit to include Coleco/Atari support, use this HACKFILE.CFG.

The jzIntv GUI could be configured as shown below. (Click on the images to zoom in)

NOTE: The GUI does not handle long directory names that have a space (e.g. Program Files). It is best to place the hackfile.cfg in the BIN direcotry where jzIntv.exe is located at and not specify a path as shown in the image below.

Testing the interface

Use these Intellivision test roms to confirm that the controllers, keyboard, or piano are responding correctly. CLICK HERE to download.

jzIntv supports 4 controllers but not 4 joysticks. If you wanted to use 4 controllers, you would need a CGC.
If you have 2 interfaces and want to use 4 controllers, use the Nostalgia emulator which properly supports 4 joysticks.

Manual modification to HACKFILE

- Mapping the ECS Keyboard - Nothing needs to be added to the hackfile for the ECS keyboard. Just press F7 to put the emulator in ECS mode.

- Mapping the Controllers - Add the lines below to map controller "A"
