Does anyone know if the Z80 instruction set is a superset of the Z8000/Z8002
or vise versa?
Z80 is an 8-bit microprocessor that uses a superset of 8080. For us old
timers, the NEC V20 processor was a Z80 compatible that had an 8080 "downgrade"
mode that would allow it to run the earlier instruction set. The Z800x series
is a 16-bit processor which uses similar instruction functions, but I'm not
sure that they're code-compatible.
