Richard: You say that memory can go anywhere on the Unibus. My question is HOW? The Unibus has 18 address lines. That means 256 Kb of memory max. The 11/24 supports 4 Mb of memory. Obviviously, they can't run 22 address lines on the 18 on the unibus. Which slots carry the extra four lines? Chris Zach PS: This problem is why there are Unibus maps, and why Q-Bus is so different.
