1 Prepare a suitable system Memory Map over the first 3K of memory, a suitable PIO configuration and associated Z80 PIO initialisation words in order to support a single electro-hydraulic system.
2 Prepare an appropriate Table of OUTPUT bit patterns for your allocated actuator sequence based on the sketch of the updated electro-hydraulic circuit.
3 Prepare a flowchart in order to aid the development of a suitable machine-code program to provide for your allocated actuator sequence.
Note: The flowchart should provide for both the specified time delays and cycle counter requirements.
Note: Assume the START button and all proximity sensors INPUT logic level '0' to the PIO when activated.
4 Prepare an appropriate Z80 Machine-Code Program based on your flowchart in Section 3.
Note: Machine Code Programming Sheets are available on MLE.
