My thanks to Tom Lovett for elaborating on my description of the
68000's internal bus structure.  My information was based on a
fairly sketchy overview article, and one I read quite some time
ago at that.

Does anybody know whether the 68020 is going to be a major internal
reimplementation, or whether Motorola is just going to graft a
32-bit bus interface onto the existing more-or-less-16-bit cpu?
I fear it may be the latter, which would undoubtedly improve the
overall throughput to some extent (in much the same way as a cache,
by improving memory bandwidth) but wouldn't have quite the crunch
of something that actually did 32-bit arithmetic 32 bits at a time.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO v IBM.
