KIM-1 Simulator version 1.1.6 has been published. Get it here.
It now supports Focal-V3D 12-AUG-77 (the Aresco version) from the KIM-1 Software page, see here.
Updates to the Simulator are a working echo suppression (see here for background). Available to any program.
For Focal V3D a setting has to be made in the Settings, to allow Focal to do its magic in the input routine.
By working on Focal I did add comments to the disassembly of what I found. You will find the original by Paul R. Santa-Marie and my partly commented version in the archive.
