Version 5.4.1 of Plaque Simulator has been designed for a Mac Pro (Intel processor), or a PowerMac G4 or G5 (PPC processor) computer running MacOSX versions 10.4 through 10.6. Please get the fastest processor you can afford. Plaque Simulator should run on nearly any MacOS computer that can run Carbon applications under MacOSX 10.4, but performance may be sluggish on older machines. Please note that MacOSX 10.2 and all earlier versions of the OS are no longer supported due to API compatibility issues. The software will likely run on MacOSX 10.3 but Eye Physics no longer has any systems running that OS so we have no way to test it.

The development systems are currently 3GHz MacPros with 6GB RAM running MacOSX 10.5 and 10.6 (Snow Leopard). Peripherals include multiple Dell 24" ultrasharp flatpanel displays, an Epson 4870 firewire flatbed scanner, Canon inkjet printers, and several workgroup class color laser printers such as an Xerox 7750 and an HP 8550 on the department's ethernet network.

• CPU: 1GHz or faster, any number of CPU cores, G4, G5 or Intel processors, Mac Pro, iMac, MacBook or MacBook Pro models.
• RAM: 1GB minimum, 2GB or greater recommended.
• OS: MacOSX 10.4 (Tiger), 10.5 (Leopard) or 10.6 (Snow Leopard).
• Video: any standard Apple supplied card.
• CT image digitizer: A "high-quality" flatbed scanner with transparency option, such as the Epson Perfection 4870. You can also import some DICOM format images directly from your CT or MRI scanner over a network. Additional programs such as Madena and Osirix can also capture many more variations of DICOM images.
• Fundus photo digitizer: Any current generation Mac compatible flatbed scanner such as those from Epson. These typically cost less than $400.
• Mouse: A multi-button scroll mouse is now standard from Apple.
