From what I have seen, yes. There is a Hex version of this board for the 8/A. the product for the E was a 2 board set. Each pair of boards had 16k X 12 bit. So two pair of boards are required. I have two pair but have some stuck bits I need to figure out.

Since the E came out before the A and DATARAM made a board for the E, and quad boards from the E would work perfectly in the A why would you make a board specifically for the A?  Did they make a Hex board version of it for the A?  Was the E a two board set?

Hope you find the documentation.
