Apple have publically stated that they 'intend' to remove support for 32bit applications from future versions of Mac OS. VirtualAcorn products run in 32bit mode and won't function on any version of Mac OS X that runs in 64bit mode only. It's worth noting that the removal of 32bit mode isn't for technical or performance reasons but is driven by Apple's desire to earn money from application updates provided via the App Store. We will look at shifting VirtualAcorn products to 64bit once Apple has provided hard and fast detail on its proposed removal of 32bit support from Mac OS X.

Required Processor
Intel 32bit or 64bit processor (running in 32bit mode) with a speed of 1Ghz or above (multi-core recommended), for example:

Intel: Core i7, Core i5, Core i3, Core2, Core2 Quad or Core Solo.

PowerPC: G4 at least 800Mhz, G5 at least 1Ghz (performance will be slower than an Intel processor with the same clock speed)

Required Operating System
VirtualAcorn products will run on any version of Mac OS X 10.4.0 onwards (provided support for 32bit applications is included).

VirtualAcorn products are not suitable for 'Classic' versions of Mac OS.

Required Memory
The absolute minimum memory requirement for G4 or G5 Macs is 512Mb of RAM. For early model Intel Macs we recommend at least 1GB of RAM. For late model Intel Macs we recommend at least 2GB of RAM.

Required Graphics Card
32Mb of graphics memory with OpenGL support. Any Intel powered Mac will meet this specifications.

Required input devices
Mouse and keyboard. Apple Mighty Mouse recommended.

Minimum 500Mb of free hard drive space and optical drive for the installation CD (The VirtualAcorn installer is designed to be portable and can be copied from the installation CD to a USB memory stick using any Windows, Linux or Mac OS X computer)
