| AvailableChecked Jul 27, 2026 | GTIA2RGBby Lotharek / AcidMaker | 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. |

| AvailableChecked Jul 27, 2026 | SpectreAVby Candle O'Sin / Lotharek | 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. Sources |

| Build itChecked Jul 24, 2026 | Ultimate Gated Video (UGV-II)by MyTek | Improves Atari 8-bit analog video and corrects overscan for modern displays. The Brewing Academy configurations were sold out on 2026-07-24. MyTek publishes the current UGV-II schematic, bill of materials, PIC firmware, and Gerbers. The 0.8 mm main board requires assembly and PIC programming. A normal installation is nearly solderless at the GTIA, but routing video to the stock DIN connector can require a few motherboard solder points. |

| AvailableChecked Jul 27, 2026 | VBXE 2.1 Familyby Tomasz Piorek, Candle O'Sin, and Lotharek | 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. |
