So don't use links ! Build a board with a transputer and some ram dual ported into the host PC address space. That said you will be pushed to get 2MB a second out of a PC/AT bus however EISA or MCA will do it. We get close to 2MB on our EISA boards using this approach however our product is not a general purpose design that you could adapt. -- John Pettitt, Specialix International, Email: jpp@specialix.com Tel +44 (0) 9323 54254 Fax +44 (0) 9323 52781 Disclaimer: Me, say that ?
