[sci.electronics] PC+AT hardware reference?

henry@utzoo.uucp (Henry Spencer) (08/21/89)

Anybody know of a good reference on PC and AT hardware and bus structure?
I don't want a maintenance manual for a particular box, or a babytalk
introduction aimed at semi-illiterate MBAs, or anything containing the
word "software" (much less "MSDOS").

What you want is the "Technical Reference for the Personal Computer AT".
It's part of IBM's Hardware Reference Library.  I've heard that it's very har
hard to get, but bootleg copies are widely available in the orient.  It
includes a complete set of circuit diagrams for the AT.

RE: Obtaining a Technical Reference guide for the IBM AT.
 
HARD????
 
Come on! They' are WIDELY available! I called IBM here locally at their
sales offices in Phoenix ..got a price list..now I have all three books.
But the price tag is EXHORBITANT. The whole schmear cost around 
  $700 from IBM.
It's **** NOT **** the availability..it's the price!

Michael Slater's Microprocessor Report also has a collection of IBM's
AT patents. They might be cheaper if you got them from the patent
office but the price is not unreasonable and buying it from MR will
probably save enough time that it really is the cheaper way to go. 

Frankly, I think IBM's tech refs are pretty lousy documentation.  They
are adequate for getting a schematic of the AT but there's a lot of
missing stuff like PAL equations and theory of operations or even
useful signal descriptions, much less timing. 

Of course, having botched up the AT bus as a standard, IBM then
proceeded to abandon it. Talk about anti-social.
