I know this is an obscure piece of Apple hardware, but I think they're neat because the color matches the old PowerBooks. I have two of these - one working and one not. Because I couldn't find any photos of the base online, I disassembled my defective unit to take a look around. For what it...

Yes, I know it's comical the amount of threads started because of the infamous IIsi power supply. Naturally, I'm joining in the fun and creating another! Hopefully this will spark more discussion around what could be the culprit with them. Okay - here's the issue with mine: it powers on, then...

I’ve been sitting on one too many Portables needing a recap. Yesterday I decided to get moving and actually complete one. Apart from these boards sucking a TON of heat from my iron, the job was straightforward. Keep in mind I did not test this board before the recap as to not cause damage to...

Yesterday I decided to open up a Color Classic I’ve had on the bench for a while. My Post-It note said that the analog board was inside, but the caps were removed… cool! I opened it up and got to replacing them. Strangely, I noticed some flux residue and fresh solder on the leads of the flyback...

As promised, I'm starting a thread for my tinkering with upgrading the internals of the well-known and somewhat hated power supplies for the Mac II/Quadra 650/700 desktops. Like many of you, I have a few of these that are dead as a doornail. For the rebuild, I've ordered three 300W Seasonic...

I was browsing and have noticed quite a few unresolved threads surrounding video/startup issues with the Mac IIci. My pledge to the forum is that when I solve my own issues, I'll post a follow-up with the solution (if there is one) ;) I've got a recapped IIci board that has a couple of issues...

I'm posting this here in hopes of eventually helping someone else out as I work to solve my own problems. Here's one I haven't seen before, it's a "simasimac" screen with the lovely addition of some video MUX issues (vertical bands). Funny thing is, the board itself is very clean. I've seen much...

Hi all, I am working on an SE/30 that works with the exception of the serial ports. Snooper 2 is my go-to for testing, as it seems to be reliable in picking up problems. The issue is, the entire system crashes when I run the serial port tests. With loopbacks connected, it'll give me the...

So, I've had this Plus for a while and haven't been sure what to make of it. I've never seen any badging done this way. It has the "square" form factor Apple logo, but with a silkscreen. The silkscreening seems to have been done professionally based on what I can see. I thought the "Plus"...

I've had this board for a while but haven't really looked at it much until recently. I have no idea what it's for, other than maybe driving an external monitor. I really can't find any information online about it either. My question is this - why would it need a 68000 processor and four RAM...

Posting this here to help document a fix that worked for me to get this machine up and running again. A few months back, I ended up with a IIsi that had some of the worst cap leakage I've seen. Lots of corrosion and missing solder mask. I don't have a photo handy but I'll try to find one (seeing...

Hi all, I decided to document my latest project board - yup, another battery bombed SE/30. Now, some photos! This is how I received it (yikes). Here's what it looked like after a very thorough cleaning. This is where I'm at now: Battery holder removed UD1 removed, cleaned, replaced RP4...

I wanted to share this beauty I picked up last night. You already know it's battery bombed (aren't they all). Here are some photos for fun. It came with a display card, networking card, and RAM of unknown capacity. I figured I'd share my progress here in the hopes that it's entertaining and...

Apologies for the click bait title... I couldn't resist! Needless to say I'm working on a troublesome SE/30 which appears to be in "jail". When I first received this board it did boot to a cursor and flashing disk, which makes this all the more frustrating. Thinking it would be simple, I did the...

I have a CD-ROM expansion module with a strange issue. It will only read discs if I hold the mechanism in place and press into the laptop. If I release, the disc spins down and unmount from the OS. Ejecting also only works if I release my hold on the door right as I hear the click of the latch...
