iMac G5 “ALS”, with auto light sensor

The penultimate iMac PowerPC fifth generation: the main thing in it – ALS, light sensor. Computers and Pets, if you do not know, live is hidden from us his own life, and carefully watching us… Some of them have learned to adjust the intensity of self-luminescence. That “watching us”, I wrote to be witty. Today’s protagonist was the last model iMac, which is not spying on us. Like a good servant, she was tracking the light level, and if not to order her not to do that, set up the screen brightness…

The new iMac G5 was announced on may 3, 2005. As “the new iMac G5, iPod; iPod can buy here…” This is not advertising, it’s a quote. It was everywhere, all over the world, in different languages. Success is contagious and everyone wants to feel in his purse drops of Golden rain.

With the exception of ALS, nothing unexpected happened. It was a speed-bump (which from and “bumps” and “routine performance improvement”). In all of this, the model ID PowerMac8,2 was cute and charming. Hundreds of these iMac’s, forever frozen on Mac OS 10.5.8 (and even earlier versions of Mac OS X) are still used…

Hero Appliances, Two double

In 2005, compared to 2004, something changed. Imperceptibly, WiFi and Bluetooth from exotics turned into something familiar and useful, and management of a world leader in the field of home computer, and now electronic, home appliance could not react to it.

Manufacturers of PC-shnyh clones started to install WiFi cards in their products, with them, the joy of paid consultants, selling routers of all shapes and colors…

But the best were those in which you had to configure almost everything, because it flexibility and manageability. That is not only a “teacher of Junior classes in retirement”, but quite capable in their difficult areas people might not know the “basic stuff”, as something thought.

In all embodiments, PowerMac8,2 support AirPort Extreme and Bluetooth 2.0+EDR included in the basic package. Step is not too high (prior to this, purchase and install the AP and BT acquired an iMac was easy – just a little extra), but important.

The may iMac G5 2005, General data

Processor – the PowerPC 970fx.

North bridge CPC945 developed by IBM and produced on 90 nm technology, the he U4 (in the notation Apple: CPC945 is a trademark owned by IBM, indicating it would have any time to mention IBM!), the ratio between the frequencies of the processor and front system bus – 3:1.

The second level cache is 512 K, the type of RAM PC3200 DDR (400 MHz) in the base package of all variants consisted of 512 Megabytes. All Macs on the PowerPC G5 was one nasty limitation: a pairwise identity of the RAM. In the case of the iMac G5, slots for its installation had two and both of them were busy with chips of 256 Megabytes.

However, the “on the spot” directly in our online store, you can increase it to the maximum 2 Gigabytes.

Increase the size of the internal memory was forced: Mac OS 10.4, which shipped the iMac G5 (ALS), worked fine with 512 Megabytes of RAM or higher and designed computer was one such subtleties do not understand.

Video card ATI Radeon 9600 (8x AGP) with 128 MB of video memory. Winnings during the transition from 4x to 8x AGP, as it is known, did not meet expectations: performance though increased, but only by 5%. But the numbers in the specifications hypnotizing therefore necessary.

Of course, since this is a home computer, an external monitor you can display only the picture from the main screen (Mirror mode). The extension of the working space is artificially blocked, scripts Firmware – corrected without opening the case and screwdriver, but in the iMac G5, in my opinion, no one fell. The case when one display is enough.

Interface hard drives – Serial ATA with data transfer rate of 1.5 Gbps for the optical drive – UltraATA/100.

As has been mentioned above, AirPort Extreme and Bluetooth 2.0 + EDR ready for immediate work, regardless of the level of computer literacy of the user. They just “already there”.

Communications: modem 56k v.92 and Gigabit Ethermet (10/100/1000Base-T).

5 USB ports – 3 USB 2.0 on the case and 2 USB 1.1 on the keyboard. 2 FW 400.
