Macintosh/PC Compatibility Guide 23
5 Running PC software on a Mac
Macintosh users sometimes need to run PC applications to exchange datawith a client, or simply because that particular application does not existon the Mac. Rather than purchasing a real PC, it is now possible to runapplications designed for Windows on a Macintosh.
To do this, you need to use a special kind of software called an emulator. Thesesimulate the presence of essential components of a PC-compatible microcom-puter on aMacintosh. Themost advanced PC emulators for Macintosh will runvirtually all operating systems and applications designed for PCs. However, toachieve that successfully requires a fast Macintosh.
5.1 Emulators
The best-known emulator is Virtual PC from Microsoft. Several different pack-ages are available ; starting from theDOSonly Virtual PC,which is only suppliedwith MS-DOS but it is very affordably priced. You can then install the oper-ating system you want (Linux, Windows 98, Windows Me, etc.) or purchasethe corresponding package: novice users may prefer the ready to use versionswhich are bundled with an operating system already installed (Virtual PC 2000or XP).
Demanding applications
To work ef�ciently, Virtual PC require a powerful Macintosh. Microsoft recom-mends at least a PowerMac G3 or G4 running at 500MHz, 256 MB of memoryand 2GB of available hard disk space. All current Macs meet these require-ments.
A real PC
When you start Virtual PC, the characteristic Windows screen appears in a Macwindow that you can resize, hide or move. Within the window, everythingworks just like on a real PC. Compatibility is seamless: standard of�ce suites(IBM Lotus Smartsuite, Microsoft Of�ce 2000) for example, run �awlessly as domost major �nancial packages and a large number of Internet utilities.
On the other hand, multimedia applications lack punch. The performanceoffered by emulators is limited to running audio or video creation applications,an area where the Mac typically excels in any case. The same applies to thelatest 3D games, which run slower than on PCs.
Virtual PC running several versionsof Windows at the same time Using Virtual PC, it is possible to run several PC applications simultaneously,
or even to run more than one version of Windows on the same Macintosh, allwith your Mac OS X applications running simultaneously.
5.2 Remote display
Emulation is not the only way to display a Windows screen on your Macintosh.Netopia's Timbuktu Pro software lets you take remote control of a PC and

display its screen on a Macintosh. To run Timbuktu you need a Mac (runningMac OS X) and a PC connected together on a network. Once the softwareis installed on both machines, the Macintosh can remotely control the PC.Practically, the PC screen is "moved" to a window on the screen of your Macand all of the actions performed on the Mac are re�ected on the PC.
You can also do the exact opposite, hence allowing a PC to take control ofyour Mac. In this case the display of your Mac is "projected" on the PC screen.Timbuktu is a commercial application but other solutions are available for free.
AT&T's research labs have developed VNC, a remote control application avail-able on almost every operating system, including Mac OS X, Windows andseveral other �avours of Unix and Linux.
You can download a free and full featured VNC server from Redstone Software(http://www.redstonesoftware.com/vnc.html) and a full featured VNC client
OSXvnc from Redstone Software called "Chicken of the VNC" from the following page: http://sourceforge.net/projects/cotvnc/.
VNCThing is a free utility which lets a Mac remotely control a Windows PCrunning VNC software, which is also free. More comprehensive and function-ally richer is Timbuktu Pro which ful�ls the same function, but this applicationfrom Netopia must be purchased.
Microsoft Remote Desktop Connection
Microsoft has released Remote Desktop Connection, an application that allowsyou to connect to a Windows-based computer and work with programs and�les on that computer from your Macintosh computer. To use Remote Desk-top Connection Client for Mac, you need network access and permissions toconnect to a Windows-based computer running Terminal Services or RemoteDesktop Services.
Once you are connected, your Macintosh will work just like a Windows PC. Youwill be able to con�gure PCs and launch installed applications.
Remote Desktop ConnectionMicrosoft Remote Desktop Connection 1.0.2 works with Windows XP Profes-sional, Windows .NET Standard Server and Enterprise Server, Windows 2000Server/Advanced Server/DataCenter Server (you will have to install the Ter-minal Services components on Windows 2000) and Windows NT Server 4.0Terminal Server Edition.

Citrix applications
American software vendor Citrix has developed MetaFrame, a server appli-cation that allows programs running on a Windows NT or on a Windows2000 server to be displayed on the screen of your Mac. The only softwarecomponent required on the client station is a small remote screen application.
Citrix has released an ICA client for their Citrix MetaFrame server. It is calledCitrix Connection Manager and is available on Mac OS X.
