A few versions of the Sheffield editor and Pascal compiler exist in
source form. Two versions of the editor in binary form exist and
work. Building the editor would require a binary copy of their
Pascal compiler. Building their compiler from source would be a bit
of a project, since iirc it's self hosted. (The Prime compiler is
available.)
