PowerMac 6100 Series

An Excellent Photo Of A PowerMac 61xx Logic Board

The battery is clearly marked in this excellent photo of a 61xx family logic board, the photo was kindly donated by Ean Harker It's cage looks just the other ones on the other Macs.

This model can easily be clock chipped from 60 to 80 MHz, and the bus speed goes up from 30 to 40 MHz. This provides a immediate improvement in speed; my sister's 61xx also has a 1024k L2 cache SIMM (from the L2 Cache Company) that boosts performance noticeably.



PowerMac 6214

Another GIF That Should Be A JPEG, Sorry This computer has a Rayovac 840 (which could be replaced by the cheaper 841) alkaline battery. The label on it says "Rayovac Computer Clock Battery" and with that red and black color scheme it is hard to miss; it is held on by velcro.

If you look closely you can see the little, red, reset button on the logic board close to the battery. The User's Guide advises that you pust that button when you put the logic board back in - and it resets the date. But not the desktop pattern, so it must reset only a part of the PRAM.

It is very easy to get the logic board out of the PowerMac 6214 - it is a lot like the MacTV and the Quadra 630 (look on the Q630 page for directions to disassemble this model). What a great design for maintenance! But that battery really holds on to the logic board - when you pull on it, the board flexes a lot.



PowerMac 7100/66

Here is the Mac - with the cover off.

Another Poor Photo That Should Be Replaced

This model uses the 3.6 volt lithium battery; the red arrow points to the battery, it normally has a cage over it but it has been removed so you can see the battery.

Here is a good closeup that shows a little more detail, with the snap-on cover still removed for clarity:

Not Another GIF!

PowerMac 7200

A Good Photo Of The Battery Here is the battery.

It uses the 3.6 volt lithium battery, to get to the logic board: press two catches (see the photo of one below, one is on each side of the underside of the front bezel) and slide the cover backward and lift off.

You can now easily remove the front bezel.

You will see two, hinged, sections - a closeout panel on the left and the drives on the right. The large section that holds the drives is held in place by two sliding catches - one extends into the front of the case and one into the rear. Move them to the center, swing the closeout and the drive section up and away and whole inside is exposed.

You will see the battery; and in this photo you can also see the RAM slots and the VRAM slots.

The next photo is of the front, bottom, of the front bezel and shows one of the catches that release the top cover:

Press On This Catch (And The One On The Other Side) And Slide The Cover Back

You can now also see the catch that keeps the bezel cover for the CD drive in place - you can carefully push into that slot and pry that curved section away from the front and the bezel will come off. The catch is that semi-circular dark area.

This is what the 7200 looks like with the drive cage swung aside:

Resolution Here Is Not Great, But The Details Are Shown

This version uses the 3.6 volt lithium battery. When I get some photos I'll put them here.
