- No, it's not; it's a microSPARC.

-
- Yes, it would have been highly amusing to watch him try to do so, but I
- think he was knowledgable enough *not* to try to do that.
-
- If he tried booting a Sun-4c kernel, it would probably have crashed and
- burned *most* spectacularly.
-
- The SPARCsystem 600MP, SPARCsystem 10, SPARCclassic, and SPARCsystem LX
- machines are all Sun-4ms. They use the SPARC Reference MMU, which
- doesn't look a hell of a lot like the traditional "Sun MMU" used on all
- previous SPARC machines and on all Sun-3s other than the 3/80 and 3/4xx;
- they also have Sun-4m style control registers of various sorts (e.g.,
- interrupt control registers), which don't look all that much like the
- equivalent control registers on Sun-4c machines (or other SPARC
- machines).
