Hi Jos\ufffd, 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\ufffdt have a Photo of my KLM\ufffds 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\ufffdt work cause of this component.
