You'll find that in many ways the Symbolics world and the Explorer
world are similar, having both come from the same roots (MIT's CADR).
The Explorer is arguably closer to the CADR in design, programming,
and operation than Symbolics's later offerings (ie, after the LM-1).

An important difference between Symbolics and Explorer systems is that
the Explorer is microcoded very differently from Symbolics machines,
mostly because the Explorer retains the 16-bit macroinstruction
opcodes that Symbolics diverged from when they developed the Ivory
architecture.  The Explorer macrocode architecture is also 32-bit and
not 36 or 40-bit.

There's lots more that you can get from the manuals on kappa.  Look in
kappa:/home/lispm for more details.
