Good news about that wire, I think. On mine, the same chip, 74LS14, that pin is unused: not connected to a trace in any way. I was going to suggest using an ohmmeter to see if maybe whomever put that there was trying to just bridge a short but when I looked that pin is unused. You can see by looking for traces leading away from it (lines) and there aren't any. You can hold it up to the light and feel certain. At least if yours is like mine. My guess is you can clip that wire off and put it out of your mind safely. Missing battery on CPU controller card (the one inch circle) is tadiran TL-5135 3.6 volt lithium, orderable here:http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=439-1024-ND the leads are shorter but still okay just have to use a solder sucker and get the holes empty first and hold it in place at least till one lead's set.. Tadiran has not made the ones will really long leads for so many years that if one did find the long lead version of the battery, it would work for 6 months or something.(Just so you don't waste time looking for them) These are new and should be good for at least 10 years. Best Regards, Glenn p.s. I have a composite monitor connection not a fairlight monitor on IIx but no pen at all, if anyone could share how to successfuly acquire/ rig a lightpen I'd be most greatful. --- Jean-Bernard EMOND <jbemond@free.fr> wrote: > Hi David, > > Le 23 févr. 08 à 21:12, dvdborn a écrit : > > after having rebuilt the CPU Controller Card I > went to pick up the > > rest of the Series IIx. > > > > It's only now that I've got the complete system > and that I can see > > what else is wrong with > > it. > > > > First thing that I'll be doing before I power it > up is to see if > > the power supply outputs the > > correct voltages and if there are some caps that > need to be replaced. > > > > The system contains the following cards: > > CMI02, CMI08, CMI01 - CMI08, Q256, Q133, Q209, > Q219, QFC9 > > > > 1.
