Fujitsu FM-8

The FM-8 (Fujitsu Micro 8) is a personal computer developed and manufactured by Fujitsu in May 1981. It was Fujitsu's second microcomputer released to the public after the LKIT-8 kit computer, and the first in the "FM" series. The FM-8 was an early adopter of bubble memory technology.

The FM-8 would later be replaced by two new models in November 1982 – the FM-11, aimed at businesses and the FM-7 aimed at the mass market.

Motorola 6809 CPU

The Motorola 6809 is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes.
