Notes:
1.
WAIT#, BVD1 and BVD2 are driven high for compatibility
2.
Shows density for which specied address bit is MSB. Higher order address bits are no connects (i.e. 4MB A21 is MSB A22 - A25 are NC).
3.
For the 3MB card the memory will wrap at the 4MB boundary, for the 5MB card the memory will wrap at the 8MB boundary.
