Certainly a good idea. I think the starting point is a SIMH debug trace of a situation
where the wrong answer is produced. As I understand it Reindert has a setup that will do
this. The KG-11 is a simple enough device that the mistake may well be obvious by
inspection given a trace that shows a broken case.
Another possibility if it's not so obvious is to convert the schematics into a VHDL
model. It could even be coupled to SIMH if one were to run it in GHDL.
