=== Unreleased XL models ===

The high-end 1400XL and 1450XLD were announced alongside the 600XL and 800XL. They added a built-in 300 baud [[modem]] and a [[voice synthesizer]], and the 1450XLD has a built-in [[Double-sided disk|double-sided]] [[floppy disk]] drive in an enlarged case, with a slot for a second drive. Atari BASIC is built into the [[Read-only memory|ROM]] and the PBI at the back for external expansion.

The 1400XL and the 1450XLD had their delivery dates pushed back, and in the end, the 1400XL was canceled outright, and the 1450XLD so delayed that it would never ship. Other prototypes which never reached market include the 1600XL, 1650XLD, and 1850XLD. The 1600XL was to have been a dual-processor model capable of running 6502 and 80186 code, and the 1650XLD is a similar machine in the 1450XLD case. These were canceled when [[James J. Morgan]] became CEO and wanted Atari to return to its video game roots.<ref>{{Cite web |url=http://www.atarimuseum.com/computers/8BITS/XL/1600xl/1600xl.html |title="Atari 1600XL" |access-date=April 14, 2008 |archive-date=September 13, 2011 |archive-url=https://wayback.archive-it.org/all/20110913014906/http://www.atarimuseum.com/computers/8BITS/XL/1600xl/1600xl.html |url-status=dead }}</ref> The 1850XLD was to have been based on the Lorraine chipset<ref>{{Cite web |url=http://archives.atarimuseum.com/archives/archives.html |title=Afterthoughts: The Atari 1600XL Rumor |access-date=September 19, 2008 |archive-date=April 15, 2009 |archive-url=https://web.archive.org/web/20090415111352/http://archives.atarimuseum.com/archives/archives.html |url-status=dead }}</ref> which became the [[Amiga]].
