Hi Jos\ufffd, i try it in your language (thx to google :) Eu signifiquei a unidade, que fornece o processador central com o pulso de disparo (normalmente uma unidade preta). Este componente \ufffd necess\ufffdrio de modo que o processador trabalhe. \ufffd poss\ufffdvel, isso que \ufffd soldado completamente perto no processador central. I hope you can understand what i mean :) Greetings Stef Jos\ufffd Pereira wrote: >Thanks Stefan >I also replaced the oscilator board KLM-508 with one from my second >Poly61...No good results... >Best regards >Jos\ufffd >Portugal > > > >----- Original Message ----- >From: "Stefan Rinass" <st@rinass.de> >To: <PolySix@yahoogroups.com> >Sent: Tuesday, March 09, 2004 10:36 AM >Subject: Re: [PolySix] Re: Poly 61 in troubles.... > > > > >>Hi Jos\ufffd >> >>I don\ufffdt know the Poly-61 and how he is organzied, but maybe the >>"PS61"-Messsage is not generated by the CPU Chip, so -maybe- the CPU >>itself doesn\ufffdt work cause of a bad connected (overall defect/missing >>"ground-line") main Oscillator (which feeds the main CPU) >> >>Pure speculations. >> >>Greetings >> >>Stef >> >> >>Jos\ufffd Pereira wrote: >> >> >> >>>Hi Gil >>>Yes, I did. >>>The CPU chips are assembled in sockets.
