[comp.arch] Request information on Harris machine

bronson@bedroom.UUCP (Mark Bronson) (08/08/89)

I gather Harris has a machine ( actually a family of machines) based on
multiple 60830s. Has anyone had any experience or know more about the
architecture of the beast?

Thanks -

My understanding is that the Nighthawk will be a follow on to their Tahoe
offering, doubling the cpu speed and allowing at least a 2 processor version.
I believe that they have OEMed Masscomp 68k workstations in the past, but
have no knowledge of an '030 multiprocessor in the works.  Wouldn't be
suprised to see one, though.

As one who has some prior Harris connections but none now, here are my
versions of the relations between the various recent (i.e. post 6024)
Harris machines:
There were some MassComp derived boxes, whose labels I've forgotten, but
the Tahoe was derived from a CCI machine. As it evolved it became more of
a Harris product, with redesigned hardware built by HCSD. An ECL version
of the Tahoe was announced but never seen.
The Nighthawk is the current product line. It is 68030 based, available
with 1 to 8 processors. It is nominally compatible with the Tahoes at an
OS level, in the sense that recompiling your source code will make it run
on the new system, but the processor is totally different. The Nighthawk
is selling now, and from what I hear is selling pretty well. It seems to
me to be aimed pretty clearly at the simulation market which has always
been Harris' strongest, with fast interrupt response, etc., and has had
some significant sales in that area: I don't know how it may be doing in
other markets.
