A 4 MHz oscillator connected to the clock pin of Z80 is fine, the only
specific called out is a 330 ohm pullup, so make sure your oscillator has
enough drive current.  You may want to buffer the clock anyway if you have
other peripherals to drive.

For such a simple job, I'd be tempted to use one of the single-chip family
MPUs (Z8, 8051, etc).
