[unix-pc.general] Service Manual

bdb@becker.UUCP (Bruce Becker) (01/14/90)

An information sheet in the "AT&T UNIX PC Model 7300 Owner's Manual"
gives a list of documentaion, among which is

	AT&T UNIX PC		528-602-0301S
	Model 7300
	Service Manual

Is this the same manual being currently sold for $100 by
one of our illustrious participants to this newsgroup?

If not, what is it?

Thanks for any info,

Illustrious, huh... :-)  

Anyhow, here's a repost of a previous article that _should_ clarify
your questions ...

I've gotten several questions from individuals confusing what each
manual is, so I'm going to try a "group clarification" on what each
is...

	----------------------------------------------------------------------
	AT&T UNIX PC Reference Manual (also known as the UNIX PC 
	Technical -or- Hardware Reference Manual) ...

	  This is the grand-daddy of all UNIX PC manuals, it contains
	  lots of information specifically the technical hardware related
	  information.   It's approximately 500 pages long and contains
	  the topics 

		a) System Features and Functions (overview of the
		   entire hardware layout)
		b) Logic Board Theory of Operation
		c) Diagnostics
		d) Logic Board Test Procedures
		e) PAL Equations
		f) Mnemonics
		g) Expansion Memory Locations
		h) Motherboard Schematics (3 sets for different revisions)
		i) Floppy Tape Interface Theory of Operation & schematics
		j) EIA/RAM Combo board & schematics
		k) International Version Reference Manual Supplement
		l) DOS-73 Co-processor Theory of Operation
		m) TCP/IP WIN/3B Ethernet board Theory of Operation & schematics

	   The manual is printed on 8.5 x 11" paper, so the schematics are
	   reasonable size.  A must for the really serious UNIX pc hacker.

	----------------------------------------------------------------------
	AT&T UNIX PC Service Manual (My copy is dated back to 2/12/85, so it 
	may have been updated after that)

	   The intended audience for this manual is the field personnel and
	   users interested in independently servicing and maintaining the
	   AT&T UNIX PC.  Topics included were:

		a) System Features and Functions (physical layout of the 
		   unit).
		b) Using the diagnostics
		c) Troubleshooting
		d) Removing and Replacing Subassemblies (hard disk, fan,
		   monitor, etc..)
		e) Part numbers for "Field-Replaceable Items"
		f) Monitor Adjustment

	    This manual (although I never had an original) I found to
	    be *very* basic.  "How to open your UNIX pc?  Where the 
	    fan is?  Part numbers?"  All which have been discussed here
	    before, or can be gotten from the Service Parts Guide that
	    comes with the Operating System.

	----------------------------------------------------------------------
	AT&T UNIX PC s4bus Specifications  (this manual wasn't ever for
	sale, it was basically available from the Product Manager when
	writing a letter to them).  Since there is no longer an UNIX pc
	in AT&T's mind, and the acting product manager probably doesn't 
	have this, nor does he want to be bothered sending it out, I
	offered it in my UNIX PC Reference Manual deal)... ~35 pages.

	    Well this manual contained some "heavy" technical information
	    about the Expansion BUS of the UNIX pc/7300.  It was probably
	    intended for audiences who wanted to build UNIX pc expansion
	    cards (ie. a company like Alloy).    The manual contains:

		a) General Description
		b) Standards
		c) Conventions
		d) Definitions
		e) Electrical Specifications (S4BUS Pin assignments, power,
		   connection specs, logic signal levels, etc..)
		f) BUS Signal Description, transfer rates, arbitration,
		   interrupt, audio signals, power signals)
		g) BUS Cycle Types
		h) I/O Expansion Card Specs
		i) Expansion Memory Card Specs
		k) Expansion Bus Master Specs
		l) Interrupt Protocol
		m) Expansion Board Identification
		n) Expansion Board Reset


There you go... that's the summary.  Hope it provides the proper information
to people that were wondering.

Being one of the turkeys who paid $150 for the "Service Manual", believe me
what you want is the "Reference Manual", which is what Lenny has, and
was $450 from AT&T.

Okay, when I bought the "Service Manual", I was on Version 2.0 of Unix
for the PC7300/3B1.  At that time it did have some timely information,
such as the pinouts and signals of the serial an parallel ports.  This
was later included in the owners manuals of later versions of the
system.  On the whole, the information in the "Service Manual" should
have ALLWAYS been included with the owner information.

The "Service Manual" has sections for a very general description of
the system, shows you how to use the "diagnostics disk", has a
section on troubleshooting (most things lead to "replace motherboard"),
tells you how to disassemble the unit, has a VERY brief parts list and
has a 2 pages on monitor adjustments.

All in all this book is about 120 pages long, yielding a price of better
than a buck a page, including the Table of Contents and the Index...
