The Risc PC Cards

Brings PC OS and PC software into a RISC computing environment
Allows Risc PC software, DOS software and Windows software to be run together

Acorn designed the architecture of the Risc PC specifically to support second processor upgrades. The Risc PC uses a technology called bus mastering which allows the second processor to use the memory and I/O of the Risc PC, thereby simultaneously keeping the cost of the upgrade down and delivering high performance.

The Risc PC Card is easy to install, a process the user will achieve within minutes and without the need for any tools. This is made possible by the innovative design of the Risc PC casing, which facilitates user expansion.

The design of the card has been a joint project involving Acorn, Future Technology Devices International (FTDI) and Aleph One. FTDI specialised in the design of custom ASICs for PC architectures. Aleph One have a successful track record in designing PC cards for Acorn 32-bit RISC systems, and the controling software which is used to set up the host for the PC card to function.
