the boot chime played and after a while the grayscale display sprung into life sadly it can't find an operating system or maybe the hard disk is dead the little trackball also seems to scroll well thankfully mobile display technology has really come a long way in the last NUMBER_TOKEN years it's also quite possible that it has degraded a bit over time as well this was being sold as for parts not working so it's quite relieving to see that at the very least it does turn on and if i can't manage to fix the hard drive i do have a spare that should fit in here so fingers crossed we can get it working before i take apart the power book i thought i'd try it in the duo dock that didn't seem to do anything so i took the cover off to make sure the laptop was seated correctly it did turn on and as before it couldn't seem to find an install of mac os the auto eject mechanism didn't seem to do anything sadly even with the laptop turned off i'm not sure if that can be fixed but i will give it a shot and to rule out the hard disk being blank and not dead i made some mac os install floppies i've linked the website i used to get these in the description below and using a free trial of win image i copied over the files this program formats the floppies correctly so that it can boot off of them i had a box of old disks so i'm glad i can finally make use of them with my fingers crossed i put in the floppy disk relievingly it did read the disc but even though this mac apparently shipped with os NUMBER_TOKEN apparently i still need a newer version so i went back and created discs for version NUMBER_TOKEN this time it showed the happy mac icon and began to start the installer and then it crashed third time lucky this time with version NUMBER_TOKENNUMBER_TOKEN it actually loaded into the installer floppy disk without any errors but it didn't detect a hard disk meaning the drive must be dead or faulty so let's open up the laptop and see if we can work out the problem getting inside one of these powerbooks looks to be pretty straightforward requiring the removal of only a couple of torx tNUMBER_TOKEN screws this then allows us to flip up the keyboard revealing the internal components from here i released the keyboard connectors and after a fair amount of trial and error i was able to detach the top casing the NUMBER_TOKEN inch scuzzy drive is underneath this blue cover my guess is it shields the drive from heat or electrical interference it turns out that the spare scuzzy drive i had lying around was exactly the same model and capacity i think i pulled it from a powerbook about NUMBER_TOKEN years ago and when turned on it didn't seem to find an operating system and when i listened closely i couldn't hear the drive spin up at all so we've likely got two dead drives and that's not ideal but i'm not giving up yet it's time to open up the original drive that was inside this laptop previously i managed to revive a NUMBER_TOKEN year old laptop hard disk by moving the heads which seemed to have been stuck the hard drive heads are small copper coils at the end of the arm that move over the magnetic storage platters but even after moving the heads a bit they still wouldn't move there
