I couldn't find a copy of the memo named "Loop Iteration Macro" by Glenn Burke and David Moon, January 1981 (MIT/LCS/TM-169) at MIT's dSpace site, or anywhere else. So I scanned in my copy and have uploaded it to my web site.
NOTE WELL: This document was written prior to CLTL and describes a facility that was available in MACLISP and the Lisp Machine's Zetalisp. Common Lisp drew design ideas from this, but the syntax, semantics, and associated functions/macros described in this are NOT the same as what Common Lisp offers.
For example, my recollection from long ago (which I did not re-check before making this post) is that there are other differences in syntax because this earlier version of Loop was underconstrained in the ordering of the keywords in a way that let you write some expressions that the committee felt might confuse people with their results.
But also, for reasons that slip my mind, Common Lisp did not adopt the define-loop-path macro that is described starting on page 19.

You can pick up the document 'Signalling and Handling Conditions' from this index page:
It was longer than I thought it would be, but I think you'll find it interesting to see what the Zetalisp condition system (which inspired the Common Lisp condition system) looked like.
In spirit, it was much the same. The biggest differences are:
* The CL system has 'active' restarts, where the ZL system had a passive thing where you returned a value to the case context and hoped that it would do the thing you wanted. It felt quite a bit more error-prone (if you'll pardon the reuse of 'error' here, maybe I should say 'mistake-prone').
* The ZL condition system offers a lot of really low-level stuff that did not seem proper for CL.
* The set of operations offered in ZL was richer, but also a lot more complicated, I thought, and I worried people would not really see what it was trying to do.
* Obviously, the ZL system was based on Flavors, not CLOS, and made reference to a lot of LispM-specific packages.
* The document was published in January, 1983 and identifies itself as part of Symbolics Release 4.0.
There are other differences as well.

@weekend_editor @charliemac @symbolics @restorante @crandel @Zenie @weavejester correct, I do recall, ‘sheet’ was the core abstraction in the #LispM window system. #CLIM made that a first-class concept, and #McCLIM still carries it forward today

> And the editor on #LispM is called ZWEI.
Well, technically... :-)
ZWEI (Zwei Was Eine Initially) was the infrastructure for writing editors, while the actual editor on the lispm was called Zmacs. In practice, nobody messed with Zwei unless they were extending Zmacs.
I have no experience of Eine, or at least no memory of it.
And yes, Zmacs was different from Gnu Emacs, which was different from all the other Emacsen before it.
