Perhaps you're referring to the Indigo^2, but the R4K Indigo has most
things in common with the R3K Indigo. Same backplane, same skins, same
graphics boards and options. IIRC the little serial PROM is different.
The PSU is uprated slightly (though some R3Ks used the same PSU) but
otherwise the same. Obviously the CPU board is different, and the
memory on it is standard 72-pin FPM SIMMs instead of the proprietary
stuff used on the R3K. In that sense only is it like an Indy.
