Hmm same result with port 0001. I think maybe I am not doing something quite right?
I have a crashDump.sys file if you would find that useful at all.
I used Ivolume to make a fresh floppy the hit D from the power on menu. It wrote a few blocks to the floppy, which I think are a dump of the memory into the crashDump.sys file. 1024 bytes.
