Under the heading of "where did *that* come from?", I've stumbled on a loose leaf binder from Motorola titled "MVME121 System Hardware Manual". There are several publications within, but the bulk of the binder's taken up by a document called "MVME319 Intelligent Disk/Tape Controller User's Manual", which contains all sorts of detail, including principles of operation, command layouts and schematics. Circa 1986. A customer must've sent it to me; I have no use for it. Anyone want it for the cost of shipping? Cheers, Chuck
