Design An Address Decoding Circuit For The Following 68hc11 System

Design an address decoding circuit for the following 68HC11 system:

  • 8KB EPROM starting at address $E000
  • 8KB socket for RAM or EPROM starting at address $6000
  • 8KB RAM starting at address $C000
  • I/O chip partially decoded to start at address $9800

This happens to be the EVB board. If you have the EVB schematic, try this question without looking at it.
