That's right, if you only use the official Z80-instruction-set,
but who does. If you use the SLIA (shift left inverted arithmetic)
as I do, you get into a conflict, because this instruction-
sequence means TSET (Z280). And this difference is even mentioned
by Zilog in it's own Z280 Technical Manual (see Appendix A)!

Unfortunately the instruction-sets of Z180 and Z280 are so much
different, that you can't use a Z180-assembler to create Z280-
opcode...

Does anybody on the net know about a Z280-assembler (or a
pre-assembler to use an existing Z80-assembler)?
