Yes, something different. Systems Concepts was formed by Stewart Nelson
and Mike Levitt, made some early equipment for the MIT AI lab PDP-10
computer, and later the successful SA-10 disk controller compatible with
IBM disks. In the 80s they went on to make the SC-30M and SC-40
computers which where compatible with DEC's KL10. But this SC-4
computer was apparently something else.
