I have a Daystar Turbo 040 33MHz accelerator that is currently not work. When putting into any one of three IIci computers I have, I just get a black screen and nothing else. I have tried swapping out the CPU for a known working one and it has not made any difference. Visual inspection shows no broken traces that I can find. Trying to fix something like this is well beyond my skill set, so I am reaching out to see if anyone out there would be willing to take a look at it and see if it can be repaired? I live in the United States, in Minnesota.

Well, I finally got around to doing more testing and it turns out the Turbo 040 had a bad ROM chip. When I replaced it with a 4.11 version it is now working again!
