it would be nice to see the virtual address, physical address, instruction space/data space flag and data for each cycle
a perfect result would be any data that would be visible and updated each bus cycle by a blinking light front panel such as a pdp11/70 doug On Wed, Sep 4, 2013 at 10:38 PM, Mark Pizzolato - Info Comm < [email protected]> wrote: > OK, so the original hardware supported single cycle stepping.**** > > ** ** > > What would expect to happen in the simulator if you stepped single > cycles?
