Well, I think that this is a good idea, so to get things rolling...

Here at the University of New Mexico, we are building a 5th order 
hypercube (32 node) using the 32032 and 32016.  Each node will contain
the following:

The items marked by a * are things that are different from
anybody elses hypercube.

	1) Compute engine
		a) 32032, (cpu - 32 bit)
		b) 32201, (tcu - timing/control unit)
		c) 32202, (icu - interrupt controller)
		d) 32082, (mmu - memory management unit)
		e) 32081, (fpu - floating point unit)
	     *  f) 8 Megabytes of DRAM
		g) 128  kilobytes of SRAM
	     *  h) running GENIX (Nationals version of 4.2 UNIX)
	2) I/O engine
		a) 32016, (cpu - 16 bit)
		b) 32201, (tcu - timing/controll unit)
		c) 32202, (icu - interrupt controller)
		d) 32082, (mmu - memory management unit)
		e) 32081, (fpu - floating point unit)
		f) 128 kilobytes of SRAM
	     *  g) 2 RS232 ports
	     *  h) ethernet controller (AMD's lance)
	     *  i) SMD disk controller (8466)
	     *  k) 5 ~10 megabytes/sec (1 direction) links

The 8Mbytes of DRAM is sudo-dual ported; that is both processors
can access it.  The 128 kilobytes of SRAM is accessable only by
the local cpu and is used primarily as buffer space for both
the ethernet and disk controllers on the I/O engine and stack space
on the compute engine.

Currently available hypercubes use serial transfers of 10 MegaBITS/sec 
whereas ours will be 16 bit parallel (at ~10 begaBYTES/sec).

Current status:

   We have both of the above wirewrapped on a vme card and are about
to start testing out our hardware design.  After that we will start
to port GENIX.  We hope to have this done in 1-2 months.
