Crystal Oscillator (Apple IIe)

Crystal Oscillator circuit using dual PNP transistor with 12V and 5V power supply In real world, this circuit works fine, this simulation works fine, too. It does not like other crystal simulation circuit and needless to toggle (On then Off) the [Start] button to start oscillation. PNP is 2N4258 originally. 2N3906 works, too.
