Got a good one for you guys...
I have an Apple's 8bit Video Nubus Card, which gives the standard 640X480 @ 256 color video from one of my IIci/cx. It needed a recapping and I gave one. 9 caps in total - 6 22µf and 3 47µf caps.
The thing with the card is this, when put into a Mac II (IIcx/ci/fx and so on) there is no video then you turn it on. Just a blank screen. After a few seconds where it should give a Happy Mac of Flashing "?" in a Disk Icon, it gives the chimes of death.
The Macs tested with other video cards work fine before and after the testing of this particular card.
Giving a recap should have fixed this card, it didn't. Traces look OK but I broke a trace on a 47µf cap forcing me to give it a pig tail repair to fix the trace. Same symptoms still occur.
Fixable? What's shorted out? I think its holding down the 5V line which RAM needs to pass a Memory Test Boot Sequence which the Death Chimes says it is failing.
