A very brief summary of the current i960(R) processor family :

Commercial:
	SA : core architecture, 16-bit multiplexed bus
	SB : SA plus on-chip FPU
	KA : core architecture, 32-bit multiplexed bus
	KB : KA plas on-chip FPU
	CA : superscalar, core architecture, 32-bit demuxed bus, dma
	CF : CA with bigger I-Cache and a data cache

Military:
	MC : core + FPU + MMU, mil-spec
	XA : MC	+ object-oriented tagged architecture, mil-spec
	MM : superscalar, core + FPU + MMU, back-side cache, mil-spec
	MX : MM + object-oriented tagged architecture, mil-spec

Note that none of the commercial parts are the same die as 
any of the military parts : that would cost too much.

Also, the MM/MX is _not_ hexagonal. It's basicly rectangular.
It is one of the larger chips made by Intel.
