Links wont cut it (unless you use 2 or more and that gets very messy).
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.
