macintosh portable

This is photo from Mac Portable non-backlight. Trying to recap and repair the traces. I noticed the 2 tinned traces coming from R22 show continuity across R22 resister. Should they show continuity? What is likely causing that if not?

MacEffects once sold an 8MB RAM Card for the Macintosh Portable. TechKnight did the original design and licensed it to MacEffects for mass distribution. That card went out of stock around 2021, and due to chip sourcing issues, it probably won't be in stock in the future. Some people who...

Since I didn't learn my lesson about my terrible design skills while trying to build a universal laptop power adapter, I recently ordered one of @Androda's Portable VGA adapters and thought, "I probably should cover this up before I damage it and short out something important". So I build a...

We previously only had the French version of MacTest 2.0 on the Garden. And while I certainly have nothing against that language, it's not my native tongue, so I prodded the gang over on FaceBook and one kind soul whipped it out of his collection and uploaded it today. It's DL#3 here...

I deyellowed my Mac Portable's spacebar using this: • 3% H2O2 (normal drug store kind) • 1 teaspoon Oxiclean (boosts the H2O2 slightly) • Small transparent plastic container. • SaranWrap (as a cover to prevent evaporation) • Aluminum Foil (place shiny side up, under the container) • Two angled...

Okay, fellow Macintosh Portable owners... I've got a question for you. Mine is a 5126 Backlit model. As we all know, the Portable has a 2-minute Sleep timer active by default, but in theory at least, you can tell it not to sleep. When running System 7.1, the "Portable" control panel has been...

Below are photos of my 5126 Macintosh Portable's Keyboard with ALPS ivory switches. (Closeup photos below show more yellow than reality. They are ivory.) Note the SQAURE PADS on either side under the spacebar. The ends of that metal support bar hit the pad rather than smack the metal frame...

Although this schematic set only covers the non-backlit 5120, much is similar to the 5126. For example, the audio section matches my 5126 Portable quite well. The Hybrid section is of course different. To download, click the blue button in the upper right corner.

NOTE! The motherboard has been ultrasonic cleaned, recapped, traces repaired, and cleaned again via ultrasonic. The Apple AC Power Adapter I am using has also been cleaned, recapped, and cleaned again. PROBLEM: I'm hearing a soft pop sound from the speaker every 10 seconds when my 5126 Backlit...

With the Vendors section going away, this thread will serve several purposes: * Reference to my store's URL * New product announcements * Product Suggestions * Product Support Tech by Androda, LLC website link This is my side business / hobby company dedicated toward trying to solve problems...

Online, you can find a lot of discussions related to what power brick to use with Macintosh Portable (the original is M5136 7.5V 1.5A), if it has to be exactly 1.5A or can be more and if it’s worth recapping the power supplies. I decided to at least somehow help in those discussions with...

I happen to own three Macintosh Portables and I was looking for a way to charge their batteries every now and then, without unpacking the computers from their safe storage. In short, I needed an external charger for Mac Portable batteries. Today, I would like to share my design of a 3d-printed...

I am curious what issues people need to be aware of when buying a Macintosh Portable, especially the backlit model (5126). I realize Portables won't power on without a good battery, but new batteries like this are sold on EBAY. Maybe some of you can share experiences with those. I also realize...

I am in process of working on a 7 megabyte Macintosh Portable RAM Card. It works in my test Portable, and I've sent one off to be tested in a Backlit portable. For me it has booted System 6.0.8, passed the Snooper RAM test, and plays games like Tetris and Risk with no issues. Why 7 megabytes...

One page document showing the pin layout for easily fabricating a 34 pin to 50 pin SCSI adapter for the Mac Portable.

In keeping with my latest string of recreations, here's another one. I am working on recreating the 'hybrid module' from the non-backlit macintosh portable because these tend to die and do stupid things thanks to capacitor fluid damage or the coating cracking off of the high precision...

Hello everyone, As we all know, flex cables for a variety devices are starting to get a little bit creaky and in many cases have cracked. Great examples of these are display cables for the Macintosh Backlit Portable, PowerBooks, and the eMate 300 (though in the eMate's case it's because of a...
