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.
