I'm repairing my Nintendo Donkey Kong arcade PCB and I have no pulse when tested with my logic probe. I found out that the crystal oscillator (2 pin HC-18U) was not connected to the board, since the legs have rusted completely and broken. The 2 pin crystal is a 61.44 MHz HC-18U model. It generates the clock for the Z80 processor.
Can I use a crystal with a different frequency, without damaging the components or affecting the game?
I can't find any two legged crystals, only 6 legs flat VCXO type... could that work?
