Atari 2600 Portable CNC-built

Atari 2600 Portable, CNC-built
Chapter 17 of the book

Build a portable Atari 2600 system with a 3″ TFT display, built-in battery pack, compact design, PS1-style joystick, paddle control and Player 2 joystick port.

This project can be constructed by using CNC-cut parts and other hobby materials. You’ll also need a soldering iron, X-Acto knife, wire, screwdrivers and other common tools.

Construction Resources

Once you’re ready to begin work on this project the links and information below will be of much help. All links open in a new window so you can easily come back here during your online part collection. This information is all contained in the book of course, but the book itself doesn’t have internet access 😉

Major Project Components

The two primary components of these projects are the original game systems, display and Sony Infolithium Type L battery. Below are the correct models to use, with a reference photo and easy-to-use automatic eBay search link.

Console model:
Atari 2600 4-switch
Automatic eBay search for this item (Atari 2600 4-switch)
Screen model:
Casio EV-680 Pocket TV
Automatic eBay search for this item (Casio EV-680 pocket TV)
Battery model:

Sony Infolithium Type L series battery – NP550 or better

Automatic eBay search for this item (Type L battery)
The higher the NP-XXX number the better. 960 is the best, 550 minimum. Automatic eBay search for Type L battery charger
Be sure it’s for a “Type L” battery, or a multi charger that can fit a “Type L”. Other 7.5 volt batteries will work, however you may have to modify the project to get them to fit.
PS1 Dual-Shock controller (for joystick)

Electronic Components Lists and Part Numbers

I’ve separated the electronics parts list into what you can get online from Mouser ( and what you’ll still need to find at Radio Shack. Therefore the two lists below are the same as the single list in the book. You’ll still need everything from both lists, but the more things you can get online from Mouser the cheaper it’ll be.

Unlike Digi-Key, Mouser’s website has no minimum order so it’s handy for the experimenter, plus they have good prices. Please note that the items for modding the Casio TV screen (10 ohm resistors and white LED’s) are also included on this list. Using this list you can easily copy/paste the part numbers into Mouser’s web site (or Radio Shack’s, below) to complete on online order. Sure beats typing!

The appropriate battery can be found by using the eBay link above.

Changes, Updates and Error Corrections

This section contains information on things that may have changed since the printing of the book, corrections to any errors found and better ways of building the projects, if applicable.

New and improved composite video mod for the Atari 2600

NOTE: Now includes update for different model Atari 2600 4-switch boards.

I came up with this as I was working on a new project. Gives a cleaner picture with less interference. Also isolates the sound circuit from the video. If you’re just modifying an Atari for use with a normal TV it also increases compatibility (with newer sets especially)

Easy way to bypass the “Stupid 8-DIP IC” found on some model Atari 2600 4-switch boards.

In the book I suggest hacking the 8-DIP IC off the board, or cutting a small section. That’s all well and good but since then I’ve found you can “remake” that circuit using only a capacitor and resistor. It’s a lot easier!
