    Iomega Zip drive : reads but does not write

    Yeah I'm not blaming the seller, I encounter this situation more and more ; people selling their dad/grandpa's attics, and don't have a large technical expertise, do some basic tests and sell things as "working" . I believe this unit saw a lot of use and there is a problem with it. Replacement...

    Iomega Zip drive : reads but does not write

    I'm glad you mention this ; I do not use the special cable, I use a regular DB25 cable I don't think this could be the problem ? Especially as the device is detected ? Also, the seller said it worked and did not have the cable either Do you know what's special about that cable ?

    Iomega Zip drive : reads but does not write

    I just scored a Iomega ZIP100 plus (parallel + scsi) for which I had high hopes However, I'm pretty unlucky these days on ebay (or we're really seeing the end of the working retro devices on ebay...) And it does not work well, despite the seller's claims. It makes a spinning noise that I don't...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Interesting ! Thanks for posting this,

    Target mode on pb100 / hdi30

    If you could find what would prevent it from auto booting on scsi ( « D » does nothing here ) that would be great

    Target mode on pb100 / hdi30

    I'll try again to get into open firmware there seems to be a "multi-boot" command, EVEN ON A WALLSTREET, that i'd like to try. My pram battery has been replaced and works even for sleep mode. I also tryied COM-OPT-P-R to zap the pram. I need to deal with one problem after the other. Clearly...

    Target mode on pb100 / hdi30

    Holding "D" does nothing good, it still boots from SCSI. MGNIAAARHHHHH O-F does nothing either ( Wallstreet PDQ ) I carefylly read the PB1xx and the G3 manuals. In fact what's unusual is to connect two laptops together. It simply not documented ; they take for granted to receiving "host" will...

    Target mode on pb100 / hdi30

    And to say something positive in all this : when the disk is recognized (even if it's thru my brutal hotplug method for the moment) this is super handy : I can access the PB100's disk super mega fast, I was able to copy all of the documents from the PB100 in like 3 seconds which would have taken...

    Target mode on pb100 / hdi30

    Is there a key combination, for the PDQ, to boot from it's own disks ?

    Target mode on pb100 / hdi30

    If you're not hot plugging, the only thing this setup does is trying to boot from the disk... Under no circumstances (spin disk or bluescsi) was I able to have the PDQ boot from it's own disks. It wants to boot from the target mode for god knows what reason. Which of course does not help at all...

    Target mode on pb100 / hdi30

    A few pictures The cable setup i'm using, black on PDQ, gray "scsi/dock" on PB100. DB25 in between. Interestingly and as documented, the dock/scsi connector has an extra pin, compared to regular hdi30. When both are connected, start traget mode on PB100, then only boot PDQ : PDQ tries to...

    Target mode on pb100 / hdi30

    Yeah, I'm always a bit scared to be the only person on earth interested by something :) Anyway I did multiple tests Whatever I do, if I connect a PDQ (MacOS9.2) to a PB100 (System 7.0.1) thru target mode, the PDQ tries to boot from the PB100 disk. So if I boot the PB100, which automatically...

    Powerbook 100

    Yes it's a matter of personal taste, the hobby allows to restore "in your own way" in many areas I always replace hard disks because I consider they are timebombs, much more so than the rest of the electronics. They are also eating a lot of power which puts strain on the rest of the machine and...

    Target mode on pb100 / hdi30

    I think I may be adding problems on top of problems by having multiple partitions in my pb100 ; but I also think something is not working like it should What I’ll do is simplify my setup by having a single partition ( scsi Id) in my bluescsi to be closer to the original ( as I have two pb100...

    Target mode on pb100 / hdi30

    Okay I feel I'm entering a sub sub niche here, but anyway :) I'm trying to understand how "target mode" works and trying to access my Powerbook 100's disk (which is a 2,5" blueSCSI) thru the proper HDI30 dock cable I've got all that is necessary - a beautiful Powerbook G3 PDQ, with HDI30 cable...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I'm currently finishing restoring a nice G4 (which is now my youngest in my collection :) ) Am I over reacting to a factory imperfection, or are the powerbook G4 (aluminium) subject to tunnel vision ? This is from 2003 !!! Clearly mine has dark corners at the bottom, and this becomes darker...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    This problem is so bizarre Air ? moisture ? heat ? Something completely different (electronic weirdness ?) My PB180 is affected, after around 30min the corner start to get dark

    VST Zip 100 Drive PowerBook G3 Lombard/Pismo DEAD

    Just for the follow up ; My drive was indeed dead, as I bought another one and this one works right away, and doesn't block the boot process with the iomega driver enabled. For my "dead" one I'm gonna try to find a PC laptop zip drive and attempt a swap of the internals, it's either that or...
