This circuit board is, according to the manual that accompanies it, a central processing unit based on the 68000 microprocessor. The manual explains further that "the CPU 68K will upgrade any 8-bit system to a very poserful 16-bit system without requiring a complete system change." Schematics in the manual are dated 1982, the manual itself is the second edition of 1985. The board and manual are in their original case and appears to be unused.
