To Wayne: I would think that if the oscillator failed that it may still run and at the slowest possible speed. In reference to the oscillator controlling speed, that would only govern the overall speed of the cpu, which would be 1MHz with a 1MHz cpu. I would check both if it were my machine. I'm tempted to put a 14MHz cpu in mine and see how high a crystal I can put in it before it finally bombs.
Having a 1 mhz CPU doesn't set the speed to 1 mhz. The speed is set by the machine itself. A friend of mine has been running a 1mhz CPU at 3.5mhz for the last 5 years. Wayne
