[comp.binaries.ibm.pc.d] Wait States

storm@cs.mcgill.ca (Marc WANDSCHNEIDER) (02/01/91)

     Could somebody with an urge to type please tell me what a Wait state is?
I have a vagues idea, but would like to learn about what they are, and how
they relate to RAM speeds, and how caches help override them....

     Any information on this, and related topics such as refresh cycles would
be greatly appreciated...

I am aware of at least two definitions:

1. It's when you are just about to talk, and you suddenly realize you
completely forgot what you were going to say!

2. Running Windows on an XT!

The best discussion I have seen of wait states and other "cycle eaters"
is in Abrash's "The Zen of Assembly Language."  .ASM seems to becoming
a lost art in this day and age of code generators and OOPS, but
Abrash's book is among the best there is for MS-DOS.
(The book is part of a three book series on assembly lang by
 Scott-Foresman publishers.  (A quasi-guess, my copy is at home)
