Few time after the Falcon 030, Atari decided to launch its successor. They worked then on the Falcon030 MicroBox.
Basically, it is a Falcon030 in a new case with a full 32bit data bus. (Remember that the Falcon030 has only a 16bit data bus). An other version was planned with a bigger case and three expansion slots.
The MicroBoxes CPU were supposed to be upgradable to a 68040.
It was never released (How typical!). Only few prototypes were produced, then abandoned when Atari decided to launch the Jaguar game system.
Atari worked for a while on a Falcon040 and one prototype was almost finished, but we can consider the MicroBox as the last attempt from Atari in the world of Computing.
You can find a photo of the motherboard at cyberroach.com.
