Very common, for example here is one from the Jameco catalogue
BTW it’s an oscillator not a crystal, quite different.

John, Andrew or anyone,
I am barely familiar with crystals, but I do know there are many different types. What is the correct part to order for part P4 (the 4mhz crystal and socket) for this 6502 board?
