The Micro 16s was designed to be a powerful package of hardware and software in a professional business system. It offered a unique architectural design for the time: interchangeable microprocessors and thus operating systems. In fact most commonly used processors were Intel 8086 and Zilog Z80.

One or two processor boards could be plugged into the Micro 16s and either one could be in control of the bus, the memory, etc.\
Fujitsu also planned to launch Motorola 68000, Intel 80286 and Zilog Z8000 boards.

RAM memory boards could be added, from 128 KB to 1024 KB, thanks to the new 256 K-bit RAM chips.\
Fujitsu color graphics video terminal was handled by an independant video processor located onto the mainboard. A standard RGB monitor could be connected as well and used simultaneously.

With the Micro 16s, Fujitsu offered a very versatile system able to oparate all of the major microprocessors of the time, and run all existing operating systems.
