    An example of such a system is the HITAC S-3800, which was instruction-set compatible with IBM System/370 mainframes, and could run the Hitachi VOS3 operating system (a fork of IBM MVS). [39] The S-3800 therefore can be seen as being both simultaneously a supercomputer and also an IBM-compatible mainframe.
