|   Yep. Found it: MIT AI Lab Memo #1040, "Scheme-86"

Actually the subsequent chip was the Scheme 81 chip.  Scheme 86 was a
single-board computer, although it could have been made into a chip.

However, no traditional OS was ever written for any of these.  The
closest thing to an OS for them was MIT Scheme that started out being
a system to run on the Scheme 81 chip, and still shows many aspects of
this heritage.

However, Scheme is no less suitable for writing an OS than Common Lisp
(which had the Lisp machines, ignoring differences between Zeta Lisp
and CL), Smalltalk, Java, or C.
