Found this site while websurfing. It's is an in-depth exploration of the innards of the Hasselblad 1000F and Kiev-88. Included is a detailed discussion of the similarities and differences between the two models, and how the cameras work mechanically. There are several detailed drawings of the parts and assemblies, and how they fit together. Also there are historical sketches of the development of the two cameras.
As the owner of a working Kiev-80 and broken Salyut-S, I thought there was a lot of great info here. I think some of this might be useful to a 1000F owner also.
