Nope, none of those type disks. The disk is a 2870 (iomec 1000) (which is what I am trying to test / repair). -- I have a bunch of docs for this. Hasn't been a need to get them on line before now, so I'll move them up in the queue. DEC actually sold them in the RK8 (not RK8E) which was a whole rack of M series modules before switching to Diablo, then doing their own (RK05)
