Hi

 

Recently managed to get my hands on a macintosh classic, but it doesn't seem to boot   If you click on this link>>> http://p.twimg.com/AvXIN3wCAAEst_u.jpg:large <<< you will see that the screen turns on but nothing else   You can hear the system itself doing something, but im not sure what.  I pressed the back button on the side to see if anything happened & yes, then this appeared >>> http://p.twimg.com/AvXJzFCCQAE6jPo.jpg:large <<<  Can anyone help me fix this so that i can get this system booting again

 

 

 

Please & thanks

Jonny...

    Hi Jonny,

     

    The first picture seems to show a grey background only. Did an arrow/pointer appear at some stage? Was there a sign of a flashing floppy icon at some point?

     

    I assume that a startup sound could be heard immediately after the computer was switched on. Could you describe the sound that you mentioned a bit more in detail? Any other sounds/tones?

     

    The interrupt button is intended for use with debugger software. The other button (the one with a triangle) is for restart.

     

    Do you have access to a startup floppy for this computer?

    Hi Jan

     

    There only seems to be a gray background & nothing else, no arrow or pointer or flashing floppy icon for that matter.  Hmmm the best way to describe the sound is continious inside the mechine, like the hard drive or something is working away !!  No i do not have access to any startup floppies, but could i download them to my computer & then copy them over onto a floppy :?

    Jonny,

     

    It is a bit confusing. The display as such appears to be working, but nothing appears on it (except for the error message when you pressed the interrupt button).

     

    To begin with, you may want to check if anything changes if you try to reset the PRAM.

     

    http://support.apple.com/kb/HT1379

     

    You could also test whether pressing and holding down the four keys Command(Apple) + Option(Alt) + Shift + Delete(Backspace) immediately after startup has any effect at all.

     

    What computers do you have access to if you wish to create a startup floppy? Any other older Mac (model?)?

    I tried resetting the pram using the link you provided, but unfortunality nothing happens.  I also tried holding down those four button but yet again nothing happens.  I dont actually have access to an older mac, but it do have access to a 2009 macbook running snow leopard & a dell dimension 5000 running lubuntu linux.

    Jonny,

     

    In Larry Pina's book Mac Classic & SE Repair and Upgrade Secrets (ISBN 1-56609-022-9), the plain gray Desktop and the error code are mentioned as possible symptoms of a faulty filter network on a Macintosh SE or SE/30 logic board. I do not know whether the same could be true for a Macintosh Classic.

     

    It could perhaps be worth checking whether the logic board battery is OK. Sometimes a bad battery can cause strange effects.

     

    Normally, an older Mac with a built-in floppy drive is used (together with Disk Copy 4.2 or 6.3.3) to create properly sector-copied floppies from (for example, System 7.0.1) disk images downloaded from Apple.

    http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/English -British/Macintosh/System/System_7.0.1/

     

    The article below indicates that it may be possible to use a Mac OS X computer (I have not tested that). It may be something similar with Linux.

    If absolutely necessary, one can even create some floppies on a Windows PC (via a special procedure, with an appropriate utility for disk images).

    Thanks for all the help so far.  At the weekend i will try creating a boot disk to see what happens.  Im also going to open up & take a look inside just to make sure everythings ok there.

    Jonny,

     

    You are welcome. Good luck! Do not hesitate to post back if there are additional questions.

     

    Also, the Macintosh Classic contains a small system in ROM, which would allow one to boot without a floppy (through the use of a special key combination).

     

    http://lowendmac.com/compact/macintosh-classic.html

     

    However, I think that it may well be a hardware issue in this case. It is probably not a bad idea to check the battery first.

     

    Please note that it can be very dangerous to work inside a compact Macintosh computer because of the high voltages involved. Such work must only be carried out by someone with the necessary expertise.

    Hi I am having the same problem with my Macintosh Classic...gray screen no mouse cursor and the startup beep coming every 5-10 seconds.

     

    I have tried to boot from ROM Command-Option-O-X but nothing happened.

     

    furycd001 did you manage to solve this problem?

     

    Have I fried my Mac CLassic?

     

    Thanks
