Dynabyte --  16K Static RAM Board

Dynabyte typically had only 32K of RAM in their basic systems. It could be static or dynamic.  So two of these board would be present.

Dynabyte 16K Static RAM

The board used TI 4404-25 RAMs. Two versions of the board were supplied (with 250ns & 450ns RAMs). There appears to be some kind of power down battery backup capability (top right) capability on the board.  The board had Cromemco style bank select capability and could be addressed on any 4K boundary.  There was also write protect capability for each 4K. Other than that I have no information about the board.  
If anybody could share the manual please let me know.
