I have now added an external antenna to the BlueSCSI inside my PowerBook 160! This doesn't seem to have been done before on a BlueSCSI, so this was a big experiment. I followed the instructions here for adding an external antenna to the Raspberry Pi Pico W, where someone followed a similar...

Hello TD! This is my first time working on a Macintosh, but I've done a lot of Arcade game repair. Ok, So my partner found a Macintosh Classic at an estate sale, and grabbed it. When turning it on for first time, nothing happened. So I took the cover off and looked closely art the boards...

I'm currently in the process of developing RAM cards for my Portable. I have successfully created a 4MB and 8MB card and both work and boot. However, I am trying to understand the issues with slow access speeds when more than 5MB are in play (1MB on the board, 4 MB on the card). Initially I...

Looking at this it makes me wonder what Macintosh board has the largest amount of capacitors upon it. An abundance makes my heart happy! And what does it mean when you get a chime but no video output from one of these? I performed a recapping and that was the result. Before the caps I had no...

Hey y’all, a few weeks ago I posted about my Macintosh SE that suddenly died while it was running. I briefly left the room, and when I came back the machine was completely dead. The fan was not spinning and the entire room smelled very strongly of burnt electronics. I immediately unplugged the...

Hey everyone, I’ve repaired a lot of Apple hardware over the years (PowerBooks, iBooks, iMacs, Intel Macs, etc.). Over the last couple of months I’ve been doing at least one repair per week, even if it’s just something minor, so I’m usually not afraid of taking things apart. That said, I’ve...

Hi everyone, I recently archived some unique Mac OS for CHRP discs (Archive.org link / Macintosh Garden). I wanted to create this thread as a place to discuss these discs and anything related to them, such as people trying them out on different systems, etc. CHRP (Common Hardware Reference...

Hello everyone, This has been a long time coming... presenting the Macintosh SE/30 Vertical & Horizontal Bars on Display "Simasima" Repair Guide!! 🎉 This is a FREE downloadable PDF document (~55 MB) filled with high-resolution pictures and technical details. You can find this PDF file...

I've just acquired a SE/30 in decent condition… super excited! Yes, I plan on pulling and recapping it asap! Any recommendations on that would be appreciated (though I am looking into doing it myself) I was hoping to get it networked so it can at least FTP to a modern machine, but it's hard to...

This is my first post on the forum, and to start off in style, I'd like to share with the community my YouTube video on the iconic Apple M0110, the keyboard that accompanied the first Macintosh! I don't want to come across as someone who takes advantage of the situation by spamming people with...

Hey all, I wanted to share something neat I picked up at VCF Midwest this year, a Tecmar Mac Drive, perhaps the first external hard drive for the Macintosh. This drive uses a serial port to connect to the Mac, and some software shenanigans to get around the storage size limitations of the...

Hello! I recently acquired what I was told was a 128k Mac, the box has labels saying 512k. It didn’t come with the accessory box, it boots up but shows a question mark floppy disc icon, I don’t have any floppy’s either. what would be the best way to easily identify what I have? I don’t know...

Manual for the Mac-Cable-Check cable & connector testing device. Contains a classic Mac cable compatibility table and pin-outs.

I would like to know on how to adjust the CRT on a Macintosh SE (800k) The picture was when I rebuilt the machine way back in October of 2024 with a replacement analog board since the original analog board failed due a bad flyback transformer and a weak PSU that was dying The right corner of...

Hello, I've been asking and searching for YEARS, and the hunt continues for someone who can repair my unique NeXT MegaPixel 17" Color Display. This is the very late-released, hard to find Trinitron version & it is essentially a rebadged Sony GDM-1632 / 1634. The service manual exists online &...

I had an orphan LCII motherboard sent my way recently that was more than happy to be alive after some trace repairs and a recap. I also happened to have a spare PSU from a customer that had no home. But I didn't have a case! what to do? simple answer, order the Creality Falcon 2 laser...

Hello all, As someone who repairs a lot of systems, the CUDA / EGRET microcontroller chip is one of those pieces that is getting harder and harder to replace. It would be amazing if these chips could be replaced by a modern solution so we can save more 68k / PowerPC Macs! I was doing some...

Hi, I have been working on restoring a Macintosh Iici for some time, and I've hit kind of a roadblock. After swapping battery-bombed motherboard with a recapped one, I have been able to install successfully an E-Machines Futura II NuBus video card, an Asante Ethernet card, a cache card, a...

Hey all, hoping someone can give me a bit of a steer on a problem I am trying to solve with an SE/30 I picked up last week. The logic board itself thankfully had a non-leaking original battery installed which I was relieved about - but the capacitors had done some pretty serious leaking, and...

One of the lesser-known compact Mac cooling fans is called Mac N' Frost. I found the Mac N' Frost interesting compared to the more mainstream Fanny Mac and the Kensington fans for the 128k, 512k, and Plus. Introducing the Mac N' Frost! Designed by Roy Hicks and marketed by RH Electronics in...
