Newton OS and Dylan

>From a posting in comp.lang.lisp recently about applications written
in Lisp:

  "Yes. I have written several apps with Mac-like GUIs on the Mac
   using MCL. I also worked on a version of the Newton OS written
   mostly in Dylan (that never shipped) whose entire user interface
   and all its frameworks were in Dylan (which at the time was called
   'Ralph' and close to indistinguishable from Scheme + CLOS)."

I emailed him and got some more info:

   "It's somewhere between 50,000 and 100,000 lines of Dylan code,
    with a little bit of Lisp (MCL - the bauhaus development
    environment was a Dylan cross-compiler for the ARM written in MCL;
    the same code base later became the Apple Dylan release), ..."

Apparently the project was canned before getting out of alpha stage
(not unlike Apple Dylan itself). It was also in the old Dylan lispy
syntax. But it is still interesting to see this type thing in Dylan.

Isn't it a shame that such things disappear never to see the light of
day though.

Chris.
