These were the 65XE and 130XE (XE stood for XL-Expanded). They were announced in 1985, at the same time as the initial models in the Atari ST series, and visually resembled the Atari ST.
Originally intended to be called the 900XLF, the 65XE had 64 KB of RAM and was functionally equivalent to the 800XL minus the PBI connection. The 130XE had 128 KB of memory, accessible through bank-selection, and the Enhanced Cartridge Interface (ECI), which was electronically almost compatible with the Parallel Bus Interface (PBI), but physically smaller, since it was located next to the standard 400/800-compatible Cartridge Interface and provided only those signals that did not exist in the latter; ECI peripherals were expected to plug into both the standard Cartridge Interface and the ECI port. Later revisions of the 65XE contained the ECI port as well. The 130XE was aimed to appeal at the mass market.
