[lispm]

> all other lisp machines

The MIT-derived ones from LMI, Symbolics and TI.

But there were a few others which might be different - like Xerox's Interlisp-D machines, BBN's Jericho Interlisp machine, Japanese attempts or some under development (like the next generation ones from Symbolics, Xerox and LMI which haven't reached the market, but were in various stages of design&completion).
