The May 2 Infoworld article on the VM 8600S (as it's called) says this
chip uses a PLA instead of microcode.  The article goes on to say that
it can be "made compatible" with the 68000, the V60, etc., by changing
the PLA.  It doesn't sound like it can be changed on the fly like a
writable control store, unfortunately.
