Hi there,

I was playing a bit with ANE opcode $8B, and found out,
that the result is also dependant on the instruction which was executed before it! I had the instruction execute on a fixed raster dot, and the result was mostly stable
(Certain bits sometimes seemed to be not stable), and if I changed the instruction before it so that the registers remained the same (like changing an STA to an STX) the result of the instruction changed. I haven't gone into details, much further.
This was on a 8501, and I wonder if one of the C64 owner would check this on the 6502?
