The RK05s I used held exactly 4872 512-byte sectors. (Remember that the V6 root file system was 4000 blocks, with 872 left over for swap.) If memory serves, the 11/50 was an 11/45 with a small amount of (for its time) very fast memory at the bottom of the physical address space. It was sold as a RSTS machine and the fast memory was just big enough to hold the RSTS BASIC interpeter.
