Hi,

I have simulating 8086 in proteus but the signal M/IO' shows HIGH only whereas I am doing read using IN instruction from a port.

Does anybody know how to solve this? I am starting to guess that the 8086 model is incorrect, can this be possible?

thanks

The signal M/IO' shows LOW only while perform a read using IN instruction from a port (or OUT, of course). Otherwise it is always HIGH.

Please look at the Proteus 8086 example, in "SAMPLES\VSM for 8086", it works well, tried. I'm using Proteus v7.10.
 

If you cannot find it ...
