RK07 repairable?

Hi. I am a bit excited. Today I inspected a RK07 that I will get "delivered" next week. It was stored in a garage for some years so there is some minor corosion. Mostly the screws are covered with "white powder" and the rack is a bit rusty. Most of the machanics seams to be made of stainless steel and some casted metal (alu?) that isn't coroded. So I am in good hope to get it working. My main concern is the glas plate from the optical positioner that is broken off. I have the plate, it is still intact. I "just" need to glue it back to the head assembly. But then, I think, I would need to recalibrate the positioner or somthing. Is it that simple? Or is this defect a show stoper? (I know to handle a soldering iron and a oscilloscope.) What makes me a bit excited is that I will get the machine that this drive was connected to too. AFAIK there whas only a UNIBUS controller for this drive. The previous owner of the RK07 says that the machine was a PDP-11 but he don't know the exact model. I know that the "sister" of this machine is a /34. This would fit to the description: Big 19" box mounted in a "low boy" rack. I hope it is a /34. I am lusting for a non microprocessor UNIBUS machine for quie some time. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
