All In One Macintosh Models

These pages hold photos of, and notes about, the All In One Mac desktop models - starting with the MacTV and covering Macs that used 68030, 68040, and PowerPC CPUs.

Remember - I am NOT responsible for any damage done to any Mac by anyone trying to replace their logic board battery!

Apple has made lots of All-In-One models - from the MacTV to some PowerMacs - the iMac is just the latest in a long series.

The MacTV was the first example of the expanded (using larger screens than the original 9 inch one) All-In-One (AIO) style Mac - and is very easy to work on. You can easily unsnap two places on the back of the case, on the bottom, remove a cover panel, and slide the entire logic board out. The MacTV shares a case design with the LC520, the LC550, and a long series of 68030, 68040, and even PowerMacs. Access to the logic board and drives in the Quadra 630 on the Centris/Quadra page is also quite similar.

A Photo Of The MacTV Logic Board The logic board, once you get it out, looks like this. When you have the board out, see the battery on the left side of the close edge (in this example). It is under a normal cage and is the 3.6 volt lithium battery. Some of the AIO Macs did use the 4.5v alkaline battery. I have some detailed photos of the disassembly that I will be adding shortly.

The TV tuner module is on the right side of the logic board, and the single SIMM can be seen standing up on the far left side of the logic board. It stands straight up instead of being at an angle like many of the SIMMs that I have seen.

Once you have the back cover off you can easily slide the hard drive out - these Macs were made to be easily maintained.

These Macs are excellent examples of design and shows how easy it can be to build a computer for quick maintenance. The logic board and hard drive slide out the back while the CD drive and floppy drive slide out the front.

The interior is all beige - you can see the front of the CD drive through the MacTV's front panel and the front panel of the CD drive is beige. I have been trying to drop in a tray-loading CD drive but it will not quite work with the original MacTV front panel.

Here is the logic board for a Performa 550:

Here are some details about how to access the user-serviceable parts for all of these computers:

To access the hard drive and logic board - look at the back of the CPU. Unsnap two tabs that stick out from the back (just push them down), and a plastic panel will snap off. Here you can see what the back looks like with the panel off.

Just slide the logicboard out. In these next two photos you can see the logic board about half way out of the Mac.

Apparently, consideration was given to putting the TV tuner in the separate hole that is visible in the back of the computer - all of the MacTV, Performa 520s, Performa 550s, etc have that hole but I have not ever seen anything installed there. It is about the right size for the MacTV's TV tuner.

The Back Of The Mac, Showing The Logic Board

To access the hard drive, pull down on the tab underneath it and slide the hard drive out.

The Logic Board Again

To access the floppy and CD drives, look at the front of the CPU.

There is a slot underneath the curved part of the faceplate, just stick a flat blade screwdriver in there (vertically) and push towards the Mac. Pull the faceplate down while pushing on the screwdriver you need to push the lip on a tab on the faceplate back enough to clear the ledge on the Mac. In the photo below you can see the E-shaped ledge that the tab on the faceplate hooks over.

The faceplate will now slide a short distance down and you can remove it. The floppy drive is on the right side of the case and the CD drive is on the left. You can lift a plastic tab under them and slide them forwards, out of the case. This photo shows them.

To reassemble - put the drives back in and align the faceplate so that it almost covers the drives, and the slots are lined up. It only slides a short distance up.
