See also: http://www.delorie.com/pcb/first.html Which is the same board.
Thank you. I notice the LED ground current is sharing a trace with the oscillator. Perhaps that is contributing to the oscillators locking? Maybe try a separate ground trace for the oscillator and the XOR/LED part? Here's the ultimate challenge: Blue-wire patching a 01005 circuit. (You can make an oscillator out of one Schmitt gate that doesn't involve any current through protection diodes. Oh, looks like Werner already posted this one.)
