Only from the outside. The architecture of the R3k Indigo CPU board is
a slightly modified Personal IRIS 4D3x. It uses the same proprietary
memory modules as the 4D3x and it even shares the same IP12 CPU
architecture denominator. The IP20 R4k Indigo CPU board in turn is a
completely different beast. It uses the same keyboard / mouse as the
R3k Indigo as well as GFX bus, but uses ordinary PS/2 SIMM memory. It is
much closer to the IP22 (Indigo2 R4k) and IP24 (Indy) then 4D3x (IP12).
A IP20 R4k Indigo can run IRIX up to 6.5.22 just like the Indigo2 and Indy.
