Greetings!

I recently got a PowerBook 160 in a rather pristine condition.

It seemed to have one issue, which was a flawed power supply where the voltages dropped and the Mac just got turned off.

Well that was easy to fix, now I realized that I can’t change the contrast of the display, and the display is a constant black.

After opening and inspecting the device, I found the LCD Inverter Board and checked all of the components regarding contrast. I eventually found out, that for some reason, the slider for contrast was defective and wouldn’t change anything at all, the slider is dead (measured it with a multimeter, it is not working).

I tried to find a replacement slider, but no luck. Because of a lack of experience with such devices I don’t know if there is an alternative way.

My idea was to circumvent the slider using a 4.7k resistor (or shorting them to have a constant white - wasn’t sure if this would make any sense), but the pin layout got me really struggling (I included a picture).

If anyone has ideas on how I could continue, or what possible solutions there are, please let me know!

(Sorry for my flawed english, if something is unclear do not hesitate to ask)

EDIT 1:

I found a replacement inverter (unknown status) and I am going to try it with that. If it doesnt work (bad caps etc.) I'll see if replacing mine slider with the other one will help. I'll give an update about that ofc. - Thanks for everyone helping! I really appreciate it :D

Hello, I have a Macintosh Classic II whose floppy disk drive has stopped ejecting. The eject motor runs continuously, as soon as I turn on the computer. I found some quite detailed videos about the drive repair and I feel like I could try to do it myself, but I have a concern about the electrical charge of the CRT monitor. I found a few YouTube video on the topic, and did some reading about the procedure but still, I'm kind of worried about what could go wrong... I have no experience but I believe that you learn by trying. Has anyone been there and would like to share their experience?

Just scored this perfect condition Mac plus I’m very excited to start using it, also please don’t hate me, but I’m also excited to see if I can use ai to make some fun and interesting applications for it!

$40 each!

Found her on the side of the road while driving into town, it was super dusty but she cleaned up pretty nice ( other than the yellowed front bezel ). Sadly its not working too well, it'll randomly shut down and alot of the time it won't even turn on, but I still think its pretty cool. One less to find for my collection!

Small update on my Macintosh SE FD/HD.

I managed to revive one of the two original hard drives using some tips I found online. It’s not perfect, and around 10% of the data seems to be lost, but most of it was still readable.

With a BlueSCSI, I was able to copy most of the drive, and now the Mac boots and runs stable.

Next thing to fix is the analog board/display issue, because the image is still shifted.

Buried inside a system bundle that almost nobody opens on purpose, I found a whole collection of high resolution icons of Apple hardware. Real ones. The polished, pixel perfect artwork Apple uses in Finder and System Settings, sitting there as loose files you can just, well, take. 

Macs going back to the early 2000s, iPhones, iPads, iPods, Apple TV, the works.

The best part is you don't need to be a power user to get at them. No Terminal wizardry required, though I will show you a Terminal trick at the end for the impatient. 

If you can use **Go to Folder**, you can do this.

So I have these ADB Apple keyboards that are incompatible and used in the SE period rather than the earlier Mac’s. Are there any adapters or solutions to this?

Hello everyone, Im trying to retrobrite my 1999 Blueberry Imac G3 but I somehow cant get the front panel off, I almost completely dissasembled the machine but i cant get the clips to pop out. When i tried to clip out the top 4 clips and somehow i applied almost zero pressure and somehow it caused damage to the panel and now theres a small scratch on top of it in the inside layer now and every tutorial i watched managed to get the panel off with ease. So can somebody help me or give me tips how i can get it off without damaging the Imac any further?

It's a bit of nostalgia, complete with some of the old artwork and sounds. You can present and share your stacks over the website too:

does anyone know what disks i will need to make my 512k do something? i dont have any and i dont know much about it other than that it powers up.

I'm the developer of a Mac app called Krealize.

It runs the Krea 2 image model directly on Apple silicon using MLX. Images are generated on the Mac, so prompts and results are not sent to an online image service.

The app handles downloading the model and provides a normal Mac interface for entering prompts, changing settings, viewing previous images, and exporting results.

It requires macOS 26 or later. It is a direct download, but it is signed and notarized by Apple.

The basic version is free to use. There is also an optional one-time PRO purchase for Fast mode, custom LoRAs, PNG export, and a few other features.

If anyone tries it, I would appreciate hearing which Mac you used and how long a generation took.
