Uh oh.  Time for an ancient history lesson.  Okay, kids, come along
and Grampa will tell you a story about the olden days.

Our story starts sometime in the mid-late 1970s when Cray introduced
the Cray-1 and defined the "supercomputer" market niche.  These
machines had large, fast (for the time) SRAM memory, high bandwidth, a
vector architecture, 64 bit integers and floats, fully custom-designed
CPU, buses, memory subsystem, etc.  They cost well over $1 million
(which was a lot more then than it is now).

Then in 1985, two companies, Convex and Alliant, created the "mini
supercomputer" niche.  Same architecture, but with some tradeoffs,
primarily in terms of memory.  They used commodity DRAM with caches,
which was slower but cheaper, and they had virtual memory, which was
slower but cheaper (because you needed less physical memory).  These
machines started around $100,000 (which was still a lot).  I worked at
Convex from 1985 to 1992, BTW.

Moore's law marched on, and sometime around 1989 or 1990 two other
companies, Stellar and Ardent, created the "personal supercomputer"
niche.  Same theme: vector architecture machines, but even more
commodity parts and an even lower price, plus they had 3D graphics.
They were about the size of a washing machine.

The problem is, RISC microprocessors were getting fast around then,
and the personal supercomputers couldn't compete with high end
workstations from IBM, DEC, MIPS, Silicon Graphics (yes, I worked for
SGI from 1994-1999) and others.  So Stellar and Ardent had a hard
time.  In 1991, they merged and formed Stardent.  Around 1993,
Stardent more or less folded.

Kubota, the tractor company, who had been an early investor in Ardent,
bought Stardent, renamed it Kubota Pacific, and redirected it to
making Alpha CPU based graphics workstations.  They sold a few and
made a little money, but eventually folded. (1994?  1995?)

Now run along, Kiddies.  Grampa needs his nap.
