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 [w] +1 (516) 589-7930 | | lenny@icus.islp.ny.us Telex; 154232428 ICUS [h] +1 (516) 968-8576 | | {ames,pacbell,decuac,hombre,sbcs,attctc}!icus!lenny attmail!icus!lenny | +------- ICUS Software Systems -- PO Box 1; Islip Terrace, NY 11752 -------+

Ok, I've got a copy of the _S4 Hardware Reference_ which has everything that you have *except* these chapters 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 Any chance that these are available separately?
