Fujitsu Micro 8 (FM-8) was introduced in 1981 as Fujitsu’s first 8-bit personal computer and the model that inaugurated the FM family. Its architecture used two Motorola 6809 processors, one as the main CPU and another dedicated to the graphics subsystem, together with 64 KB of RAM and 640 × 200-pixel graphics in eight colours. One of its most unusual features was the ability to use bubble memory for external storage through removable cartridges, an uncommon technology that failed to gain traction and was abandoned by Fujitsu in the later FM-7.
