The RESET signal is an inverted version of the {{overline| | The RESET signal is an inverted version of the {{overline|RESET}} signal, and is produced by one of the inverters in IC15. The purpose of this signal is unclear since any peripheral could derive it by inverting the {{overline|RESET}} line itself. In the +3 it is connected via a 10k resistor (R76) to the floppy drive select line. This however seems to be an error in the circuit design though it has no adverse effects. |
