GENERAL DESCRIPTION
The Z86C11 microputer (Figures 1 ~nd 2) introduces a new level of sophistication to single-chip architecture. pared to earlier single-chip microputers, the
Z86C11 offers faster execution; more efficient use of memory; more sophisticated interrupt, input/output and bit-manipulation capabilities; and easier system expansion.
