Raises an Atari 600XL from 16 KB to 64 KB with a compact external parallel-bus module.

The page reported four modules in stock on 2026-07-27. The 600XL supplies the required 5 V through its parallel bus, so this exact module needs no external power supply.

Adds five 1090XL-family expansion slots to an Atari 600XL or 800XL through the rear parallel bus.

The page reported one system in stock on 2026-07-27. The 50-pin parallel cable is included, but a compatible 9 VAC Atari power supply is not. Expansion cards and the optional 12 V supply configuration cost extra; the seller says no currently available card needs that optional 12 V rail. Systems are assembled on demand and may take several days to ship.

Expands an Atari 600XL or 800XL to 320 KB through the rear parallel bus without opening the computer.

The Tindie page reported one unit in stock on 2026-07-27. A 600XL supplies power through its parallel bus. Most 800XL computers do not, so the board provides a jumper-selectable USB-C or wired 5 V input. Follow the seller's internal-versus-external power procedure and jumper setting for the exact computer.
