C20 - Snyder C

[larsbrinkhoff]

I'm still not entirely sure about this, but I think this is Snyder's C compiler, library, and linker ported to TOPS-20. Some files make references to Johnson's PCC, and MIT people say they they added a PDP-10 code generator to it. But these files closely match the ones found on ITS and SAIL.
