2cpu+math = 12 MIPS
8cpu+ " =100 MIPS ?
100/12 = 8.5
8/2 = 4.0
I need a math accelerator and a good one too :=).

The wisest thing Gould (ever) did. Early in their mini manufacturing
line they opted for THE operating system UNIX. To tell the truth,
porting software into UTX (Gould's name- I wonder why everybody likes
to change the name UNIX but always stick an X) is a lot easier
than even on VAX(4.3) at times. Watch out for their secure versions too.
Choosing UNIX early on the game has its advantages. The problem of OS
for a new machine is porting rather than development. That saves a lot
of time in the development cycle of an OS for your machine.
To quote somebody from Gould (Latest UNIX/WORLD),
Q. Why did Gould choose UNIX when IBM has neglected it?
Retort. UNIX is bigger than IBM.

True. But don't rule out RISC. It is becoming an industry standard.
(only the name not the technology).
Soon, the RISC name should be forgotten if every processor is a RISC
processor.

Year of new architectures! Watch out for Cydrome, Multiflow (VLIW),
Vitesse, Chopp(sullivan), ETA, RP3 ........ Architecture design
is becoming an art. Maybe we should have arch-art exhibits.
(One is coming up in Santa Clara during the first week of May).
Oh! What's new column: AI has infiltrated compiler technology.
C86 C compiler (for PCs) (Ref: UNIX/WORLD) has optimizations based on
AI techniques. Guess the consequences. The compiler learns.
The more times you compile the better is your optimization resulting
in a single line of code.
