Apple last updated the Mac mini in Late 2014, moving to a 1.4 GHz dual-core low-power Intel i5 CPU that can Turbo Boost to 2.6 GHz on the entry-level model and a very powerful 2.6 GHz i5 on the “better” Mini (power hungry users can upgrade that to a 2.8 GHz i5 or 3.0 GHz i7). System memory can no longer […]
Apple reinvented Apple TV in Late 2015, no longer hiding the fact that it has an operating system. The 4G Apple TV has a 64-bit A8 CPU and a full-fledge operating system, known as tvOS. It’s also designed to run games and includes Siri.
Although the Classic Mac OS remains useful, it’s getting hard to find at a reasonable price. We hope these links help you do so, whether for System 6, Mac OS 9.2.2, or something in between.
The Mac LC/Performa 580 shipped with 4 MB soldered on the motherboard and two 72-pin SIMM sockets for memory expansion – twice as many as the LC 550 and 575 – for up to 52 MB total system memory, the most possible in any 500-series Mac. Like other 500-series Macs, it has a slide-out motherboard.
The Quadra 605 (and its twins, the LC 475 and Performa 475/476) has 4 MB of RAM soldered to the motherboard and a single 72-pin SIMM socket for memory expansion. It supports up to 36 MB of system memory.
The LC 520 and Performa 520 are twins, larger versions of the all-in-one Macs of the past. They have 4 MB soldered on the motherboard and a single SIMM socket for memory expansion. Like other 500-series Macs, the 520 has a slide-out motherboard.
The Mac TV is pretty much a black LC 550 with a built-in TV tuner and a remote control for the TV portion of the computer. It has 4 MB soldered on the motherboard and comes from the factory with a 1 MB 72-pin SIMM in its only memory socket. Mac TV only had one […]
The Mac LC III and its 33 MHz siblings – the LC III+, LC 460, and Performa 460 – have 4 MB of RAM soldered to the motherboard and a single 72-pin SIMM socket for memory expansion.
The Mac IIvx, Mac IIvi, and Performa 600 were odd ducks, running a 16 MHz motherboard when most of Apple’s other machines were already faster than that. Since the IIvi had a 16 MHz 68030 CPU, that wasn’t a bottleneck, but the IIvx and Performa 600 had 32 MHz CPU, which were hobbled by the […]
The Color Classic has 4 MB of system memory soldered to its motherboard. There are two SIMM sockets that can be used to expand it to 6 MB, 8 MB, or 10 MB.
The Mac LC 550 and 575, also sold as the Performa 550 and 575 to the home market, have 4 MB of RAM soldered to the motherboard and a single 72-pin SIMM socket for memory expansion. They can handle up to 36 MB of memory.
The Centris 610, Quadra 610, and Apple Workgroup Server 60 have 4 MB of RAM soldered to the motherboard and two 72-pin SIMM sockets for memory expansion as far as 72 MB.
The Centris 650 has 4 MB or 8 MB soldered to the motherboard; the Quadra 650 has 8 MB on the motherboard. Each has four 72-pin SIMM sockets for memory expansion.
The Quadra 800 and Apple Workgroup Server 80 have 8 MB of memory on the motherboard and a single bank of four SIMM sockets for memory expansion as far as 136 MB. This was one of the first generation of Macs to use 72-pin SIMMs.
The Mac LC II (a.k.a. Performa 400, 405, 410, and 430) has 4 MB of RAM soldered to the motherboard and room for two additional SIMMs. (Apple says that some LC IIs have 2 MB of onboard RAM, but I have never run into one.)
The Mac Classic II (a.k.a. Performa 200) has 2 MB soldered to the motherboard. There are two SIMM sockets, which can be used to expand this Mac to a total of 4 MB, 6 MB, or 10 MB.
Personal computing never would have gotten started if not for the invention of microprocessors, which puts a computer’s CPU (central processing unit) on a single chip – sometimes with companion chips. Intel released the first commercial CPU in 1971, and the first 8-bit “home computers” arrived just a few years later.
Prior to 1986, the best Mac had 512 KB of memory with no expansion path, a 400 KB floppy drive, and no standard way of connecting a fast hard drive. The Mac Plus, introduced on January 16, 1986, changed all that.
The Quadra 900 and 950 have no RAM on the motherboard and 16 sockets for four banks of memory expansion. They shipped with 8 MB and can support up to 256 MB of system memory – twice as much as any previous Mac.
The Quadra 700 has 4 MB soldered to the motherboard and one bank of 30-pin SIMMs for memory expansion, allowing up to 68 MB of system memory.
The Mac Classic has 1 MB of memory soldered to the motherboard. A second megabyte is added with a memory expansion board, which also has two SIMM sockets. Using these sockets, RAM can be expanded from 2 MB to 2.5 MB or 4 MB.
The Mac LC has 2 MB of RAM soldered to the motherboard and two SIMM sockets for upgrading memory to as much as 10 MB.
The Mac IIsi is essentially a more compact version of the Mac IIci with no NuBus expansion slots and operating at a reduced CPU speed. It uses the same architecture, sharing the first 1 MB of RAM for video and computing.
Apple broke the speed envelope with the Mac IIfx – the 40 MHz 68030 CPU on a 40 MHz data bus left everything else in the dust. Because it needed faster memory than any previous Mac, it used a special 64-pin dual-ported SIMM. It was the first Mac to ship with 4 MB of RAM.
The Mac IIci took the popular Mac IIcx design and replaced its 16 MHz logic board with a 25 MHz 68030-based design. New features included built-in video and a Level 2 (L2) cache socket. The IIci was the first Mac with “32-bit clean” ROMs.
The Mac SE/30 shipped from the factory with 1 MB installed. It can be upgraded to 2, 4, 5, 8, 16, 17, 20, and 32 MB* configurations using 120ns or faster 1 MB or 4 MB 30-pin SIMMs – and as high as 128 MB using 16 MB SIMMs.
The Mac IIcx was Apple’s first compact model in the Mac II series, essentially a Mac IIx with three NuBus expansion slots instead of six and a smaller power supply. Like the Mac II and IIx, it can only access 8 MB of memory under System 6 and earlier. You need to run some version […]
The Mac IIx was Apple’s first 68030-based computer. You need to run some version of System 7 to have access to the 32-bit option and use the free Mode32 utility to let the IIx run in 32-bit mode. This allows users to use more than 8 MB in the IIx.
The Mac II was Apple’s first modular Macintosh. Using a 68020 CPU instead of the older 68000, it can address far more memory by using 32-bit addressing. Although it took System 7 to provide the 32-bit option and Mode32 to let the Mac II operate in 32-bit mode, this allowed users to use more than […]
The PowerPC platform had a long life on Macs. The first Power Macs arrived on March 14, 1994, 10 years after the first Mac – the Power Mac 6100, 7100, and 8100, running the PowerPC 601 CPU at speeds of 60, 66, and 80 MHz respectively. The PowerPC G5 came to the iMac in August 2004, over […]
The Mac SE shipped from the factory with 1 MB installed in the form of four 256 KB SIMMs. It can be upgraded to 2 MB, 2.5 MB, and 4 MB configurations using 150ns or faster 1 MB 30-pin SIMMs.
Dan Carlin’s Hardcore History is one of my favorite podcasts. Then again, I majored in English, history, and philosophy in college, so I like history to begin with. If you enjoy history at all, I think you’ll find this podcast a treat.
So, recently I learned that Apple, as much as I love them, may be thinking of ditching the ol’ headphone port on the iPhone 7. I don’t know how to feel about this, as I once believed the iPod/iPhone to be one of the best media devices on the planet.
The Mac Plus shipped from the factory with 1 MB of system memory installed in the form of four 256 KB SIMMs. It can be upgraded to 2.5 MB and 4 MB configurations using 150ns or faster 1 MB 30-pin SIMMs.
I love the original iPhone – but at nine years old, it really has had it’s day.
