Teardown

Introdução

NeXT Computer was founded in October of 1985 when Steve Jobs was forced out of Apple by John Scully. He started NeXT as a high-end computer company targeted at the University/Scientist/Computing Industry. NeXT only ever released , the NeXTStation, and The NeXTCube, in different variations. NeXT computers were high-end workstation computers, and only a few thousand were ever sold. The NeXTStation featured a, though the Turbo NeXTStation featured a68040. There were color and non-color variations of the NeXTStation. The world's first web server was created by Tim Berners-Lee, at CERN on a NeXTCube. NeXT computers were used to make games like Doom, and Wolfenstein. This is my&W NeXTStation. Mac OS X Is based off of NeXTStep, the NeXT OS.

O que você precisa

Este teardown (desmontagem analítica) não é um guia de reparo. Para reparar seu/sua NeXTstation, use o nosso manual de serviço.

    • Turn the NeXTStation around, and remove this screw:

    • Then, lift the top cover of the computer. This will reveal the guts.

    • The ports from left to right: SCSI2, Keyboard & Mouse, DSP Port, DB-19(MegaPixel Display), DB-9(Serial), RJ-45(Ethernet), Coaxial (10b2 Ethernet), Power

    • I find notes in everything!

    " Keyboard & Mouse"

    Nope! Those are serial ports. The keyboard plugs into the monitor, and the mouse plugs into the keyboard.

    Also the DB-9 is the printer port, by which the NeXT laser printer was attached. I don't think it could be used for general serial communications. On the other hand, if I recall correctly the DSP port *was* usable for high-speed serial communications.

    • Removing the hard drive:

    • The NeXTStation uses a 50-Pin SCSI Hard Drive up to 4GB.

    • Remove all of the cables from the logic board.

    It's incredible how modern this board looks, despite its being so dated.

    • Then remove this screw.

    • Once the screw is removed, pivot the drive up on a 45 Degree angle, then slide it out.

    Wow, it is so easy to take everything out!!! Now there are milions of screws and connectors, turning devices around and so on... I'm amazed of the simplicity!

    • Removing the floppy disk drive:

    • The NeXTStation uses a non-standard 2.88MB 3.5" floppy drive, though it uses the standard floppy connector.

    • Remove the floppy cable.

    • Then, remove this screw.

    • Now, set the board aside.

    • Power Supply:

    • Remove this screw.

    • Lift the power supply up, and out.

    Editar

    The power supply is the (only?) weak spot on this beauty! It is always the MOSFETs which burn out. So make sure you use heat sink compound when you re-assemble it!

    If it is broken, maybe this page can help: http://heller.no-ip.org/~heller/NeXT/pow...

    • The Logic Board Overview:

    • The Board has a 25Mhz Motorola 68040 CPU, This board features a ton of chips for something made nearly 20 years ago.

    • The CPU: Motorola XC68040RC25

    • The Co-Procesor: MB610313

    • Motorola Chips

    • Intel Chips

    • AMD Chips (Intel and AMD In the same computer?)

    • Fujitsu Chips

    Editar

    I think the MB610313 is a DMA controller ASIC.

    • Made in the USA, you don't see this anymore.

    • The Serial #

    • Looks like my NeXTStation came from WilTel.

    • It is model # N1100

Amazing!

MB610313 - ICP (Integrated Channel Processor). Basically DMA on steroids for almost all of the main sub components of the system. I believe that the cube, or at least the 25Mhz 030/040 cubes, had two of these.
