    I have this old 80C188EB-25 5V 25MHz Intel Microprocessor.

    I want to fire it up but I am not sure what kind of Crystal it needs.

    I am running a 50% Duty cycle.

    I know I do not want a Third-Overtone Crystal.

    What kind and what MHz Crystal do I need?

    I have used this place for over 30 years. Just tell them what you've told us, and you'll have your crystal in a few days. Always been reasonable and quick.
