Bill Have you ever given any thought to emulating the Intel iPDS system running ISIS-II ?
They were the white and black portable little brother of the MDS family. We had one once, which we called Big Blue because of its sheer physical size. Those MDS 8" floppies were really something. Going to 5 1/4 inch on the iPDS was so much nicer, but man, could those iPDS disk drives make some noise when the disk had an error and it did a track 0 recalibration of the heads. You *KNEW* that you had a bad disk !!! Fun times ...

The problem with the 'E' command will take more time. I am currently in the middle of rewriting the Intel Microprocessor Development Systems (MDS-i and II) simulators.
