They weren't the giant DEC-made PDP-10s, AFAIK. They were System Concept clones of the PDP-10 (SC30, SC40). Relatively small, modern (for the time) semiconductors, SCSI I/O, Ethernet & FDDI network. There were also PDP-10 clones called TOAD from a company called XKL that were sold into the 80s and maybe 90s. Both were much, much faster than the original PDP-10s.
