Processor Technology 16K Dynamic RAM
This was Processors ill-fated attempt at making a dynamic RAM board.

 Processor Technology 16K Dynamic RAM Board   

Not having learned from the mistakes MITS made in designing a dynamic RAM board, processor technology came out with this board. Unfortunately it did not work reliable in some S-100 systems.  It had the unusual feature of a horizontal ground bar across the front of the board. The board could be addressed on any 4K boundary.  It pulled the S-100 ready line (pin 72) if it needed extra time to refresh memory.
The manual for this board can be obtained here
