Q: Getting Data Off Performa 577

Hi everyone -

 

I've got a circa-1966 Performa 577 that worked a couple years ago when I last powered it up.   I just tried powering it up again, and not much happens.  Flipping the on/off switch in the back results in a "static electricity discharge" sort of noise from the monitor area, but no other discernible sounds.  No lights light up anywhere on the machine.  

 

Is this a sign of a dead power supply?  I tried putting in a new PRAM, just to rule that out -- but no change in status.

 

I've removed the drive (SCSI) and am now wondering how I could go about getting data off the drive (there's not a lot of data; these drives only held 320MB, and I doubt I filled 1/3 of that).   I don't have other vintage Macs to drop a SCSI into.

 

Hints/suggestions are much appreciated!

 

Thanks!

    Oops:  of course I meant a 1996 computer, not a 1966!

    Yank the drive and get a SCSI to USB adapter. You should then be able to pull your data off that old drive and onto any modern Mac. Or a PC, I suppose.

     

    I didn't find one when I searched on Other World Computing's website (macsales.com) but I saw a bunch on eBay and at some other retailers. Just be sure you're getting one with the proper pinouts, termination, and power supply.

    If you could give the name of a city near you we could maybe find a user group near you.  Several people have found local help by connecting up with old timers who keep spare computers around. 

     

    Computer recycling companies will sometimes have old external SCSI optical drives.  Pull the optical drive out and you have a hard drive bay. 

     

    As for the computer, have you tried the keyboard power switch?  It may sound like a dumb question but those computers did not come on with the power switch.  They turned on with the keyboard, after the power was supplied to the motherboard.  That is the first noise you are hearing, the CRT responding to power on.

    That was an interesting anomaly.  The text did not post.

    John,

     

    Thank you for the update.  I just found a video that might be useful on the original topic:

    Thanks for the suggestions!  I'm in the metro-Boston area.  

     

    So, the sound (like a static discharge/crackling) from the monitor suggests that the power supply may, in fact, still be working?   I have hit the "power up" (arrow-looking) key on the keyboard, but there is no response.  I suppose the keyboard could be toast, or perhaps it's the logic board.   

     

    I like the idea of trying to put the drive into an old optical drive.  I'll have to look around for one of those (or an adapter cable).

    I am not one to jump to suggesting a new PRAM battery because many computers allow for a 'warm boot.'

     

    Because the keyboard wakes up the computer by signaling the startup sequence, the warm boot does not work.

     

    Have you tried zapping the PRAM?  Hold down the P+R+command and option keys while turning on the power switch.  The brain cells are getting rusty on how that model responded to different commands.  It was an odd approach that fortunately was not used on other models except the all-in-one power PCs like the  5200.

    My recollection is that those models used the rocker switch as a service switch only, and the action begins when you press the tringle-Icon-key on the keyboard.

    Grant,

     

    Thanx for the confirmation.  I know that if a computer chimes and starts without the monitor, a keyboard reset will often wake the monitor up, even if there is a dead PRAM battery.  In fact, the dead battery is why the monitor circuit is not waking up.

     

    However, with the all in one computers, they need the wakeup/startup from the keyboard.  You can not reset something that has not started in the first place!  I have forgotten if those models have a reset on the motherboard.  I will have to dig one out and see what options they had.  Been too long (then again, it has not been long enough) since I used an old all-in-one.

    cybersooz,

     

    Here is the update.  I dug out a couple of 550s and put them through the paces.  The first one chimed, took a while for the monitor to light up and then gave the flashing question mark.  The LEDs on the keyboard should light up.  The chime should sound, the light on the lower front panel near the volume buttons should light up, the hard drive should spin up and then it should find the system folder.

     

    The hard drive did not spin up at first.  Then it did it was struggling.  The restart keys are 'command' and 'control' and the 'soft power key' held down at the same time.  The chime should sound again.  It took three or four times before the hard drive sped up to the proper speed.  It has been sitting for a long time.  Dead PRAM battery does not stop it from booting.

     

    Started the second CPU.  No chime but raster to the monitor.  No hard drive noise.  One swift hit to the right side of the computer and the hard drive started up.  No system folder so all it did was flash the question mark.  A couple of keyboard resets did not work but the speaker crackled to life after the third reboot.  Pulled the drive and was reminded that the hard drive has a multi-blade adapter on back.  Those contacts must be cleaned to insure good connections.  A pencil eraser will do the trick.

     

    Good luck.

    Thanks, everyone, for your very helpful answers and suggestions.  I wanted to update you on what I did.

     

    Well, the machine was unbootable (even with hitting the triangle power switch on the keyboard, and even with replacing the PRAM battery).   A friend tested out some of the innards with a voltage meter.  High voltage was getting in, but no low voltage was getting to things like the fan, etc.  So I suspect the power supply on the machine is history.

     

    Thankfully, I found a coworker with an older Mac tower with a SCSI interface that he had added, and he also had an external SCSI hard drive.   We managed to open the hard drive case and replace his hard drive with mine, and he was able to retrieve my data for me and burn a CD.   Hurray!  

     

    So, although my Mac is now history, I got the data that I wanted from it.   Lesson to us all:  When updating your machines, make sure your data makes the transition with you!

     

    Thanks again for all your help!
