Description
The Z86C11 microcomputer (Figures 1 ~nd 2) introduces a
new level of sophistication to single-chip architecture.Compared to earlier single-chip microcomputers, the
Z86C11 offers faster execution; more efficient use of memory; more sophisticated interrupt, input/output and bit-manipulation capabilities; and easier system expansion.PORT 0 (NIBBLE PROGRAMMABLE) 110 OR A 6-A15
