| | ===== RC2014 Signal Definition ===== |
| | |
| | The predefined RC2014 signals remain the same. The spare signals are connected to the following Z80 signals: |
| | |
| | RC2014 Pin 37 (Spare 1) — nBUSRQ (Z80 pin 25) |
| | |
| | RC2014 Pin 38 (Spare 2) — nWAIT (Z80 pin 24) |
| | |
| | RC2014 Pin 39 (Spare 3) — nNMI (Z80 pin 17) |
