The World Wide Web is a vast place, and not all of it is suitable for children. I take a look at the Supervised User option in ChromeOS, aimed at keeping them away from the nasties of the Net while on a ChromeBook.
With the October 2005 introduction of the 2.5 GHz Power Mac G5 Quad, Apple had introduced the most powerful PowerPC Mac ever. Whatever was to replace it had to be a real powerhouse – and the first Mac Pro certainly was.
I take a look at Chrome OS and the 11” Samsung ChromeBook Series 3 XE303C12 from 2013.
With macOS Sierra, Apple has once again raised the bar on which Macs can install and run the newest version of the Mac OS. But as sometimes has happened in the past, there are workarounds that make it possible to install Sierra on some unsupported Macs.
For the first time since Apple released OS X 10.8 Mountain Lion in July 2012, Apple has dropped support for a number of older Macs that had supported OS X 10.8 through 10.11 El Capitan. No MacBook and iMac models prior to Late 2009 and no MacBook Air, MacBook Pro, Mac mini, and Mac Pro […]
Introduced in January 1984, Apple’s Macintosh changed everything – but the world of personal computing was nearly a decade old, and Apple was already successful with its Apple II line. These articles look at Apple before the advent of the Mac, as well as the broader world of personal computing.
Trevor Wale shares his thoughts and experiences of this Macintosh world that we all know and love.
Tommy Thomas shares his interviews with some of the people who keep the oldest Macs – those built around Motorola 680×0 CPUs – alive and useful.
I take a look at the EnerPlex Surfr battery case for the iPhone 5/5s with a built-in solar charger.
Apple has just released iOS 10 – but how does it fare on the lowest supported iPhone?
Until 2001, September 11 was just another day on the calendar. The unexpected terrorist attacks on the Pentagon and World Trade Center shocked us and had us glued to the news throughout the day. Except for the heroes and newscasters, almost all of us stopped what we were doing, watching in shock and horror and […]
There are three different business models in the PC, smartphone, and tablet industries. The most widely used model is for one company to make the operating system and license it to a host of hardware manufacturers. This has given us the Windows market where no matter how badly PC makers do, Microsoft remains profitable.
Apple just announced iPhone 7 and iPhone 7 Plus, but will you be upgrading just because they are new?
One of the greatest games ever created, Doom. I check out the iOS port.
There are several kinds of Duo Docks of two main types: The full docks, such as the Apple Duo Dock, take the Duo inside much like a tape into a VCR; full docks provide ADB for keyboard and mouse, video, floppy, SCSI chain, two NuBus card slots, and two serial ports.
The Apple Power Mac Processor Upgrade (APMPU) is a PowerPC 601 upgrade for 68040-based Macs that have a 32-bit LC processor direct slot (PDS) – the Quadra 605/LC 475/Performa 475-476, LC 575/Performa 575-578, LC 580/Performa 580-588, and Quadra 630/LC 630/Performa 630 series.
This is the Unofficial PowerPro 601 Homepage. The PowerPro is an upgrade card that was manufactured by DayStar Digital and sold both under the Apple and DayStar brand names. It enables some members of the Quadra series of Macintosh computers with a Motorola 68040 CPU to be upgraded to a PowerPC 601 processor.
Supporting the exchange of information about the DayStar Turbo 601 PowerPC upgrade card manufactured by DayStar Digital. This page has not been updated since January 1999 and is published here as a useful historical resource.
The Apple Power Mac Upgrade Card (APMUC) plugs into the 68040 Processor Direct Slot (PDS) of the Centris 650, Quadra 650, Quadra 700, Quadra 800, Quadra 900, and Quadra 950 and provides PowerPC 601 power. With an adapter, it also works in the Centris 610 and Quadra 610. It is not compatible with 68040-based Macs […]
The DayStar Turbo 601 provides full PowerPC 601 performance and compatibility – it even provides faster performance for 680×0-based applications. The Turbo 601 was available in 66 MHz and 100 MHz versions for the Mac IIci, Mac IIsi, and Mac IIvi/IIvx/Performa 600.
Getting an old (2002) 700 MHz iMac G4 with just 512 MB of memory up and running reminded me of what a nice – and still useful – operating system Mac OS X 10.4 Tiger is, especially on that old Apple PowerPC hardware.
Yes, Android is the top selling mobile platform around the world. Yes, Android dominates the low end of the smartphone and tablet markets. So why do you see so many iPhone and iPad cases and accessories when you go shopping?
The Google Chrome story began when Google introduced its new Chrome browser in September 2008. Initially it was Windows only, for XP and later, and Chrome was only for Windows until 2009. It was finally released for Mac OS X and Linux in May 2010.
The Quadra 840av has no system memory on its motherboard and has four 72-pin SIMM sockets for memory expansion to 128 MB.
The Centris 660av and Quadra 660av are identical except for the name plate. They have 4 MB of RAM soldered to the motherboard and two 72-pin SIMM sockets for memory expansion.
Whether marked Quadra 630 DOS Compatible, LC 630 DOS Compatible, or Performa 631 or 640, these models have 4 MB of RAM soldered to the motherboard, two 72-pin SIMM sockets for memory expansion up to 52 MB, and usually a DOS Compatibility card as well.
This page provides information about modifying the motherboard in your Quadra, Performa, or LC 630 series computer. Such modifications are not authorized by Apple. Any modifications you perform on your Mac may damage it. Modifications are done at your own risk.
Whether marked Quadra 630, LC 630, or Performa 63x, this model has 4 MB of RAM soldered to the motherboard and a single 72-pin SIMM socket for memory expansion up to 36 MB. (The DOS Compatible version and some 630s have a different motherboard with two SIMM slots and are covered on a separate page.)
In recent weeks we’ve done an in-depth look at Mac floppy disk formats, published a 5-part series on Palm, launched a Facebook group for Newton users, looked at memory upgrade options for long-discontinued Macs, talked about the Mac Color Classic, and looked at some of the more obscure Mac clones from the mid-1990s. Earlier this […]
