MADE 24: Memory Address Enable 24: This line indicates when an extended address is used on the bus. If a memory cycle is in progress and MADE 24 is inactive, an extended address greater than 16MB is being presented; if MADE 24 is active, an unextended address less than or equal to 16MB is being presented. This line is driven by the controlling master and decoded by all memory slaves, regardless of their address space size. MADE 24 is driven with a tri-state driver.

hmm, so during a read operation, the data is never driven onto the bus (the output stays pulled up to FFFF). looks like the MADE24 line is staying low? that's weird. let me try making the logic ignore it.
