Folks, Hmm. I checked TOPS-10 7.04 monitor source codes and found two files about SCS/SCA packet info but did not find any files about CI interface. I think TOPS-10 can communicate through DECnet.
I think that transport layers are SCS/SCA layers. There is commercial emulator (Charon-VAX) emulates CI hardware and HSJ50 controllers. They are much faster than actual CI hardware. So that we can implement them on SIMH and other emulators possibly.

Correct. Only the HSC50 ever supported 576-byte sectors, and only on RA81 and smaller drives. (We really wanted RA82s on our 4-system CI cluster at Stanford LOTS, but were informed that it would never ever happen.)
