PC Card

PC support will be provided through the PCI bus.
Aleph One are looking at a range of third-party cards, which they will integrate with their existing Acorn drivers.
The basic PC PCI card consists of a processor, memory and a PCI interface. This does mean that the PC and Phoebe will have separate memory systems.
The PC card will be able to talk to the Phoebe peripherals and drives by taking temporary control of the PCI bus.
This method of PC support has already been adopted by the likes of Apple and Sun.
