Radius Precision Color 8-24X behavior on IICi

[mapomme]

Solved !!!!!!! and... so happy to say that !

I replaced the UH1 - 74ALS240 and voilà ! the graphic card now works perfectly !!!
In fact the corrosion I noticed on the UH1 when I recaped the mac was much more severe than I imagine under the chip.
Now everything is clean and my IIci is saved !

Thanks to all !
