Essentially the XE were not much of an improvement of the XL series. The XE utilized technology from the 1400/1450 XL computers such as the FREDDY chip for memory management. The ECI (Extended Cartridge Interface) was nothing more then the XL Parallel Bus Interface (PBI) repackaged to cut costs. The keyboards were mushy feeling and the keys were white and tended to get dirty quickly, and the function keys were on a 45 degree angle making them clumsy to use at times, the 65XE's lacked an ECI all together.
Although sold as a GAME
SYSTEM, the XEGS was a repackaged Atari 65XE with Missle Command built
in. However the one nice feature of the system was the detachable
keyboard. With the exception of the unreleased Atari 65XE-P
Portable (Luggable) computer, the Atari XEGS was the only Atari 8-Bit computer
system to ever have a detachable keyboard.
