Found in an ancient American documentation, this circuit can generate signals up to 40 MHz for a Z80, microcontroller widely used at the time. The circuit must be powered with 5 V and also serves as a shield.
This source gently applies the voltage to the load, causing it to rise slowly, thus avoiding...
