   Are you such a moron that you cannot read a simply-worded statement?  I did
not say "The ISU bus offers good performance [period]."  I said that the 8-bit
version of the ISA bus offers good performance with the 8088, and the ISA bus
itself (which is the 16-bit "AT" version) offers good performance with the
80286.  Nobody except you will deny these statements.  

   Take a look at the following statement by me:

>>   Granted, the industry had to wait a while to get a bus standard that offers
>>good performance with the Intel 32-bit processors,

   See what I said?  I agree completely that the ISA bus offers terrible
performance with any Intel 32-bit processor.  The ISA bus was designed for the
80286, after all.  Using any 16-bit ISA bus with a 32-bit processor will get
you terrible performance.  

   BTW, there was a several year gap between when the first A2000 accelerators
became available and when the A3000 became available.   During this period,
people had to put up with 32-bit '020 or '030 accelerators on a system with
the 16-bit Zorro II bus.
