Adds digital RGB, optional 31 kHz scandoubling, display corrections, and an 80-column overlay while retaining the original GTIA.

The product exposed a login-or-register-to-buy path on 2026-07-27. Update its initial firmware before installation. A socketed GTIA may still require careful removal of the adapter's bottom socket for height; a soldered GTIA must be desoldered. The May 2026 hardware manual is explicitly a draft. The product page publishes a complete VGA pinout but leaves the 15 kHz connection diagram unfinished, so do not improvise a SCART or RGB-monitor cable from that page. SECAM computers use an incompatible FGTIA pinout and are not supported.

Sharpens video on some PAL or NTSC Atari 600XL and 800XL boards by disconnecting one filter capacitor.

The recovered 2017 discussion says to lift or cut one capacitor leg, making later restoration possible, and the author tested PAL and NTSC machines only. SECAM compatibility is unresolved. Several commenters report that later Revision D 800XL boards omit C56 or use a different layout, so identify the exact board revision and component before changing anything. The quoted 80 percent improvement is the author's subjective estimate, not a measured specification; more complete video upgrades may produce better output.

Replaces the 4050 video buffer and routes configurable conditioned video signals to the Atari's output connector.

The product exposed a login-or-register-to-buy path on 2026-07-27. Installation replaces the 4050, connects GTIA pin 21 to the board's color input, and rewires output signals at the computer's video connector. A non-socketed 4050 and the output modification require desoldering and model-specific board work.

Adds NTSC composite video to tested RF-only vintage computers with a small internal solder-in board.

The JCM page offered kit and assembled two-packs with an Add to Cart path on 2026-07-24. Documentation is for North American NTSC hardware. The 600XL procedure cuts one side of the RF-output resistor and can restore RF only by resoldering it; the installer must verify all connections against the host schematic.

Adds clean composite and S-Video output circuitry to supported Atari 8-bit computers.

The Atari 8-bit Rev. D page said Now shipping on 2026-07-24 and offered plug-in, basic, kit, and 1088 variants. Installation still requires soldering, output jacks, and the ability to follow a schematic. The vendor calls its large manual a starting collection and warns that not every machine has explicit or fully current instructions. The separate 600XL monitor port and BOBby audio/video breakout are installation accessories, not standalone upgrades.

Adds RGB output, enhanced graphics modes, a blitter, and true 80-column text to supported Atari 8-bit computers.

The XL and XE product pages both exposed login-or-register-to-buy paths on 2026-07-27. Choose the machine variant deliberately: both storefront descriptions say an XE adapter is included, but the installation manual explicitly says the XL and XE ANTIC adapters differ. Installation requires ANTIC removal, an adapter soldered to the motherboard, several model-specific signal connections, and an EXTSEL safety check that may require modifying a Freddie pin. The current manual documents 800XL, 800XLF, XE, and XEGS paths, not 600XL or 1200XL.
