Risc PC 486 Card: Product Announcement
Risc PC 486 Card - January 1995
The Acorn Risc PC 486 Card:
- Runs Windows and DOS software
- Brings PC software into a RISC computing environment
- Allows Risc PC software, DOS software and Windows software to be run together
Acorn has 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 Acorn Risc PC 486 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, Aleph One and FTDI (Future Technology Devices International). Aleph One have a
successful track record in designing PC cards for Acorn 32-bit RISC systems, and FTDI specialise in the design of custom ASICs for PC architectures. The DOS operating system and manufacturing capability will be provided by IBM.
