I posted about this a few years back, but rather than resurrect a very old thread which didn't go very far, I will begin anew.
I received a IIci several years ago that came with dead Nubus slots. As it did not work, it got shelved for another day. Well, the day came last week, as I have been recapping some of my older machines of late, and thought that I would give this one a try and see if new capacitors fixed the problem. Alas, recapping the board did not fix the problem. The board has been thoroughly cleaned and has been dried.
The IIci's Nubus slots are getting power (a light on an ethernet card shows that), but no Nubus cards work and none are reported by utilities to be present in the slots. Drivers are present in software (7.1). I have confirmed this in another Iici.
The defective machine otherwise boots and seems to run just fine, oddly enough.
What is the most likely cause? I am assuming the big Nubus controller chip just south of the Nubus slots, or else one of the Bus Transceivers, making it unfeasible for me to try to repair the board (better soldering equipment required!). Could it be something simpler, and so repairable, or am I best to cut my losses and part out the machine? It has a working PS, a decent case, etc.
