Intellec MDS questions

I have the schematic of the cable and adapter board somewhere but I won't have time to look for them anytime soon. The adapter board has some tricky wiring on it and IIRC the cable IS NOT straight through. I've had a hell of a time getting non-Intel disk drives to work in the MDSs. I have quite a few of the same model drives (with different revision boards) and I haven't gotten ANY of them to work in a MDS. Yes, I've set all the jumpers. I've spent at least three days trying various drives but never could get one to work. My suggestion is to search out an Intel drive in the surplus places. Intel sold a LOT of these systems and there used to be a lot of them in the surplus equipment places. Joe At 08:01 PM 4/6/05 -0500, you wrote: controller and cable to the backplane for a disk drive. Do you have a schematic for the PCB and a wiring diagram of the PCB to backplane cable. I have some old SA801 drives and a power supply that I could use.
