The only major problem is booting Fiasco on the SCC. You will have to
write a simple boot loader that uses the SCC's tools to write all the
boot modules into the SCC's memory. After that it is rather
straight-forward, except for the special page attributes the SCC
supports, if you want to do message passing.

Regarding the code, maybe Markus (CCed) knows more.

You don't need a special compiler for the SCC. Any version of gcc or
clang will work if you set the compilation target to Pentium.

Yes, I believe we did. Markus?

Btw, what do you want to achieve? The SCC is an abandoned and buggy
platform.
