Finally had a chance to look at this. The 6204 error message is documented
in the EDUSYSTEM 50 guide here:
See page 6-49:
"6204 Error in reading the compiler, FDCOMP. Must be stored under
And yes, the library account (2) is missing FDCOMP.SAV, and I know of no
existing copy of this code anywhere, unfortunately. Perhaps it will turn
up somewhere someday, on a DECtape gathering dust on someone's shelf. I
really do wish more TSS/8 stuff was out there, but I suppose we should be
thankful that any of it survived.
