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.
