Jim, I have another D9090 that I have not yet tested nor is it the one described in my website blog post below, but it came from a trusted source who knew what he was doing, and I have posted pics. It's not a 9060, but the relevant parts to this discussion should be wired the same. Note that the LED cable connectors appear backwards, but I guess that's how it was supposed to be. http://www.vintagecomputer.net/commodore/IEEE_drives/D9090_sn2074/ I hope will help with cable orientation. I don't have a D9060. Bill Jim Brain wrote: > I've just acquired a CBM D9060 HDD. The logic board would not power > up, and I found the 5V power supply rail was not generating any > voltage.
