Conflicting Instructions: Use of 3.6V Zener Diode vs. 33k Resistor for Proper Operation

[zoushiyin]

Hi @No0ne,

I have encountered conflicting instructions in the documentation regarding the correct component to use in a specific part of the circuit. According to one diagram, a 3.6V Zener diode should be added, but another section of the documentation suggests using a 33k resistor instead to ensure proper operation.

Here are the details:

Documentation Reference: [https://minuszerodegrees.net/keyboard/ps2pico.htm]
Specifically:

Which method (using a 3.6V Zener diode or a 33k resistor) is the correct approach for this circuit?
Are there any specific conditions under which one component should be used over the other?
Could you provide any additional context or clarification on why these two different components are mentioned?
Any guidance or clarification would be greatly appreciated. Thank you for your help and support.
