The Atari Mega STE was Atari Corporation's last ST series machine. Taking something from all the 680x0-based machines they had produced, they had the idea to create a more business-like version of their main machine using the new features of the STE, the actual case designed for the TT, plus some other features.

The MEGA STE is based on STE hardware. Physically, the 2 MB and 4 MB models shipped with a high resolution mono monitor, and an internal ACSI hard disk (the 1 MB model included neither a monitor, hard disk, nor hard disk controller). Despite offering better ST compatibility than the TT, it also included a number of TT features, from the ST-grey version of the TT case with separate keyboard and system unit, optional FPU, a VMEbus slot, two extra RS232 ports (all 9-pin rather than 25-pin as previous models had), a LocalTalk/RS-422 port (no AppleTalk software was ever produced) and a 1.44 MB HD floppy support. Support for a third/middle mouse button was included, too.

A unique feature of the MEGA STE was the software-switchable CPU speed, which could run at 16 MHz, or 8 MHz for better compatibility with old software. An upgrade to the OS was also included, initially shipping with TOS 2.0 and later 2.6/2.06.

VME bus brought some interesting boards enhancing the computuer's capabilities such as graphic cards or Ethernet connection.
