Road Apples & Second Class Macs

, Dan Knight, 

Second Class Macs are Macs you should buy with your eyes wide open – if you buy them at all. The only ones I would put on the “avoid at all costs” list are those with three or four apples. The Macs with only one or two apples can be very nice computers as long as […]

Help Out Low End Mac

, Dan Knight, 

Low End Mac (LEM) has in April 1997 as a way for me to learn Web design and to help Mac get the most out of their Apple gear. There weren’t many online resources yet, and we grew from two dozen profiles to hundreds. LEM began as a hobby, was my full time job for quite a […]

CPUs: PowerPC G3

, Daniel Jansen, 

Arthur, legendary King of England, became the code-name for the third generation PowerPC (PPC) processor, eventually named the 740 and 750. The successor of the 603e, the third-generation CPUs were optimized to run real software, not some theoretical ideal. Early benchmarks show the 750 outperforming the 604e, making it look like the older chip would be reserved for multiprocessor […]

CPUs: PowerPC 604 and 604e

, Daniel Jansen, 

The “power user” second generation PowerPC (PPC) CPU was the 604, unveiled in December 1994 along with the 603. Containing 3.6 million transistors, drawing twice the power of the 601, and with a dual L1 cache (16 KB for instructions, 16 KB for data), this workhorse could deal with four instructions per cycle. The 604 […]

CPUs: PowerPC 603 and 603e

, Daniel Jansen, 

The second generation split the PowerPC (PPC) line into entry level 603 and power user 604 chips. The 603 has only 1.6 million transistors, draws about half as much power as the 601, has two smaller caches (8 KB for instructions, 8 KB for data vs. a 32 KB unified cache in the 601), and […]

CPUs: PowerPC 601

, Daniel Jansen, 

The biggest change in the Apple product line prior to 2006 was the transition from Motorola 680×0 CPUs to the PowerPC (PPC) family of CPUs. Designed by a consortium of Apple, IBM, and Motorola (a.k.a. the AIM Alliance) and based on IBM’s POWER architecture, PowerPC became the most widely used RISC (Reduced Instruction Set Computing) processor with […]

1.4 GHz iMac: What Is Apple Thinking?

, Dan Knight, 

We’ve published our first article on the Mid 2014 21.5″ iMac with its 1.4 GHz low-power dual-core i5 CPU, and Chris Carson was not impressed with its value. I want to treat is as fairly and unemotionally as possible, so let’s take a closer look.
