Converts Sophia or VBXE RGB video to VGA inside a 1088XLD.

The project publishes schematics, Gerbers, source, and PIC12F1572 firmware, but requires a separate GBS-8200 board and mechanical installation. Firmware 1.2 is beta, high-resolution modes are untested, and its rudimentary presets do not work with every monitor. The maker notes that Sophia2 is generally the better universal VGA and DVI solution.

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.
