Industrial Micro Systems - 80186 CPU Board
This is one of the few 80186 boards for the S-100 bus.  A fairly rare board.

By this time IMS had matured into a state of the art S-100 board manufacture. This looks like an extremely powerful single board computer S-100 board.  Unfortunately I cannot locate a manual for this board. If you have one or a .pdf file I will be pleased to place it here for others to use.
