I used to have one but was different to the one listed on ebay. The one I had can be seen at this link : http://www.groenenberg.net/gallery/view_photo.php?set_albumName=album14=PIC00045 Here you can see the armature with the strip mirrors, which would be moved between the platters. The diskpack would rotate slowly and you would be able to inspect each surface using the tilted mirrors. Ed -- Ik email, dus ik besta

There should be a black tube with a lens and a right-angle mirror. The right-angle mirrors are in those comb shaped accessories. Those are a set of long skinny mirrors that can swivel. You insert that device between the platters, turn the mirror to show the surface of interest, and spin the pack to look. I don't remember them being used with a telescope to magnify the view. I suppose you could use a standard microscope designed for large spacing between lens and object. paul

Re: DEC disc pack inspection unit on eBay
I'm not sure if the hub is an RP04 style or RP03 style. Yes, the accessories say big pack. Given that there is also a tool for looking at 5-ish platter packs, RP04 and later (with the smaller tool used for RM03 packs) is plausible. I remember seeing one of these in use, for inspection not cleaning. The only pack I ever saw cleaned in the field was an 1311 pack that had been splashed by leaking hydraulic fluid from the head actuator. Cleaned off fine with isopropyl alcohol. paul > On May 10, 2019, at 12:31 PM, Brian Roth via cctalk > wrote: > > I could not find it in my DEC maintenance aids handbook. > I would agree that it is definitely for multi platter drives. >On Friday, May 10, 2019, 12:23:23 PM EDT, Guy Sotomayor Jr via cctalk > wrote: > > From looking at the accessories and the spindle, I believe that this is for > examining multi-platter packs such has those for RP03/4 and RP06 and the > like.

Re: DEC disc pack inspection unit on eBay
I could not find it in my DEC maintenance aids handbook. I would agree that it is definitely for multi platter drives.

Re: DEC disc pack inspection unit on eBay
From looking at the accessories and the spindle, I believe that this is for examining multi-platter packs such has those for RP03/4 and RP06 and the like. It’s a useful find for folks who have those drives and packs and wish to actually use them. ;-) TTFN - Guy > On May 10, 2019, at 8:59 AM, W2HX via cctalk wrote: > > What is this used for?
