    PowerBook 520c Screen Issues

    Wow, that’s quite an offer. I’ll PM you then. I truly hope you can get it to work. First computers like that are hard to part with or see broken. You’ll have to promise me you show me the results of your testing with it though!

    Supermac Spectrum/24 III questions

    I should be able to, though I need to get a new chip programmer as mine bit the dust. When I do get a new one @Jamieson, I’ll let you know and hopefully get that bin file for you.

    PowerBook 520c Screen Issues

    If you really want it then I’d be willing to do a trade. At least for me, I’d send you the whole upper case since trying to carefully send just the screen probably would not go well with our post office. (Tend to not be the kindest on boxes) For me, this second 520 is just taking up space...

    Supermac Spectrum/24 III questions

    Fellow Spectrum/24 III owner here, I can't seem to find the v1.1 rom for you online but I do have the rom in mine. It may take me some time but I may be able to dump it. Does the 1.0 rom limit anything that you know of?

    PowerBook 520c Screen Issues

    Bringing this post back from the dead now that I’ve actually done what I said I would do. I swapped the display once again in my working 520c with its working cable and the same thing happened. I may crack it open to check for leaky capacitors but the fact that color is showing for that brief...

    PowerBook 520c Screen Issues

    Interesting @AEChadwick. I haven’t tested anything yet but I’ll keep that in mind when I go to test it. Hopefully since I lost today, I can respond thoughtfully tomorrow.

    PowerBook 520c Screen Issues

    So I’ve built a 520c from parts that are known working except the display. I have never had this display work but it seems to have some life in it. It briefly shows colors before going all black so I’m wondering if it’s something with the inverter board or the cables. Any help is appreciated. Emmy

    Putting the “Power” in a PowerBook

    Hi everyone! After having success with nabbing a PowerBook 520c for cheap, I wanted to push its limits and see what I could make it do. Its little 25 MHz 040 wasn’t enough for me and after acquiring a 33 MHz 040, I craved something more of this machine. I had heard that PPC accelerators were...

    PowerBook 520c will not power up

    I’m continuing off of this one as it doesn’t seem to make sense creating another one on the same machine. Ok! I just got the cable for my PowerBook 520c and after plugging in the cable and trying a disk, no spinning noises or it being ejected. It will only come out if force eject it out. I’ll...

    PowerBook 520c will not power up

    It’s ALIVE Both the ram and cpu are working just great with the new brick. And I can now confirm it was the old one. Guess it’s time to make a new one with the cable. Since I now have some extra parts, along with an entire lower assembly, I’ll test the parts and sell them here someone else can...

    PowerBook 520c will not power up

    I recently just got a new cpu and ram for my PowerBook 520c and went to try the new processor and it wouldn’t even spin up. Switching the cpus back does nothing either. It relies on it’s old ac adapter and I don’t know where to start to get it working. Any ideas to start? :( Emmy

    PowerBook 5xx ram mod?

    Hi everyone!  I got my hands on a PowerBook 520c a little while back and was wondering with the ram card kind of expensive and hard to find on eBay, could I get 2 8mb ones (identical cards of course) and combine them on one board to make a 16mb card? If so, would it be practical? Any answers...

    Jerry Rig a Battery

    Hey everyone! Got a quick question to ask, I'd like to replace my 1/2 size AA battery with a cr2032 or AA setup. How would I go about doing either? Is it a simple solder? Thanks :)
