| The following quote[1] from Frank Soltis seems to agree.
|
| ...", but the RS/6000 was just an AS/400 without the I/O processors as
| UNIX cannot make use of the capabilities of I/O processors. Thatÿs why

The only part I'm not getting is WHY the RS/6000 would have been the machine
for "compute intensive scenarios".  Given that they were/are running on
essentially the same processor.  Internal IBM politics?  Or OS tuned better?

I agree.  Now, I'm not over-sold (to put it mildly ;-) on Linux.  But I'm
REAL glad to see iSeries in the Linux press...!  Yer lucky I don't have time
to get into the other subject. ;D !  (Plus, I hope to keep you in suspense
until (if and when) Chapter 1 comes out...!)
