Actaully, the geometry of the RK05f is the same as the RK05, it just 
appears as 2 drives. Each 'drive' has the same number of cylinders, 
heads, and sectors as a normal RK05.

Was there ever a 16 sector version of the RK05f for the PDP8? I've only 
ever seen 12 sector ones.

Somewhere I have at least one manual on the RK01. I seem to remember that 
was an 8 sector device, but I certainly wouldn't put any money on that :-)
