Hi José,
i mean the Oscillator which is connected to the 8048/8049 CPU directly
(not the Oscillator Board). It must look like that:
www.phasereffect.com/img/osc1.jpg (Picture was taken from Oldcrows,
sorry, i don´t have a Photo of my KLM´s nor a Camera at the moment).
My opinion is: If the "PS61" message is really -not- generated by the
CPU, then it could be possible that the CPU doesn´t work cause of this
component.
