Default Re: Non-working Commodore PET 3016

If those voltages are as they should be, could you then let us have a well-lit overhead image of the right hand side of the PCB - especially the area I have marked with a red box on the attached image of the layout.

Try to get the image sharp and in focus as we need to be able to read which ICs are fitted and which ones, if any, are missing. Bear in mind that the forum reduces any attached images to 800 * 600 resolution, it may be necessary to attach the original image as a .zip as well so we can see the detail.
