For the second time in years, I've obtained a copy of the SGI Hardware Developers Handbook, Release 2.0 (05/97). This book covers all SGI products from the earliest Personal Iris through the Origin 2000/Onyx2. It details Chassis; Interfaces (serial, keyboard, mouse, parallel, disk drive, monitors, memory, graphics, video, audio, CPU, Bus, backplanes, network connectors, I/O Panel Plates, Drive Sleds); "hinv" output descriptions (complete); Software & Hardware tools, etc. This book was created for SGI hardware designers - but is a terrific source of information for all SGI buffs and collectors. The copy I picked up years ago is worn from a great deal of use!!! The copy I just obtained is brand new - with no markings or scratches other than one very minor nick on the bottom of the front cover. Before I put it on "ePay", I decided to offer it to this list first via the Vintage Computer Marketplace: http://www.vintagecomputermarketplace.com/bid.cfm?ad=2009 I normally would not post my own auction item on this list - but this is one of those great finds that one seldom gets an opportunity to pick up...
