In a vague sense, it is, but actually, the SE/30 is really much more like the Mac IIx (the SE/30 is basically a miniaturized IIx stuffed inside an SE). Aside from the CPU and a few other minor things, the SE/30 and LCII (and by extension, the Classic II) have almost nothing in common, except they're both Macs (and in the case of the Classic II, they're both Compacts), and both can run the same software on the same OS, more or less.
