File extension sit is mainly associated with Fortran-77 compiler (Load-and-Go Fortran-77 Compiler) developed for DEC PDP-10 mainframe computers developed by Steven's Institute of Technology.
A .sit file stores sources for compiler.
The PDP-10 was a mainframe computer manufactured by Digital Equipment Corporation (DEC) from the late 1960s on; the name stands for "Programmed Data Processor model 10". It was the machine that made time-sharing common; it looms large in hacker folklore because of its adoption in the 1970s by many university computing facilities and research labs, the most notable of which were MIT's AI Lab and Project MAC, Stanford's SAIL, Computer Center Corporation (CCC), and Carnegie Mellon University.
The PDP-10 architecture was an almost identical version of the earlier PDP-6 architecture, sharing the same 36-bit word length and slightly extending the instruction set (but with improved hardware implementation). Some aspects of the instruction set are unique, most notably the "byte" instructions, which operated on arbitrary sized bit-fields (at that time a byte was not necessarily eight bits).
Source files can be usually opened using any text editor.
Fortran parsers may be of help here.

The sit file extension is associated with some emulators that allows users to emulate and run programs written for 8-bit computers called ZX Spectrum developed by the Sinclair Research.
The sit file stores memory snapshot.
Use compatible emulator to work with *.sit files.
Probably cannot be converted to other formats.
