    dallink.zip (~62kb) (c) 1995 by David Lindauer
    The sources of a linker are less spread, I think, but here they are. No compiled .exe, unfortunately.

    vallink.zip (~145kb) Val Experimental Linker (c) 1989 by David Troendle, updated in 1995 by Dave Dunfield
    The “C” source texts look very unusual, the cause being a multitude of Pascal-like macros. No idea if any compiler can swallow them. Nevertheless, the compiled .exe is present. Linker produces mz .exe, .com & .sys executables from .obj & .lib files.
    Source text: .c (Turbo C)
