Quarterdeck QRAM only did that with NEAT or LEAP chip sets from Chips &
Technologies, by using the shadow RAM mapping, and required 1MB on the
motherboard, not 640K. I didn't think that was a significant enough
market share to mention.

It would also work with a LIM 4.0 EMS board as I mentioned earlier.
