Hello all, I need any technical information anyone may have for this hard drive controller board, especially schematics. I have all the other technical docs for the Kaypro 10. This board is not in the documentation I already have because it was not considered to be field or factory repairable. WD 1002-HD0 61-031050-00 REV Y 8, 1893 Western Digital It connects via 40 pin IDC and ribbon cable to the Kaypro main board and to either 1 or 2 ST-506 10mb MFM drives. LSI on board includes WD1014AL-00, WD1010AL-00, WD1015-00, and SY2128-2. I've already searched the web and found some general information, some helps, most doesn't.
