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?

(*LONG*) |Keywords: manuals, unix-pc, reference, s4bus, service |Message-ID: <1019@icus.islp.ny.us> |Date: 8 Nov 89 17:45:33 GMT |Organization: ICUS Software Systems, Islip, New York |Lines: 93 |Xref: icus unix-pc.general:5335 comp.sys.att:7807 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. -Lenny -- | Lenny Tropiano ICUS Software Systems lenny@icus.islp.ny.us | | {ames,pacbell,decuac,hombre,sbcs,attctc}!icus!lenny attmail!icus!lenny | +------- ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752 -------+

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... - Roger
