So they're stepping a 286 very slowly and sorta... bit-banging the I/O pins on it?

Love it. No notes.

I've seen a similar project a while ago and thought this was about the same thing at first: https://forum.vcfed.org/index.php?threads/286-cpu-experiment...

Both essentially built a DIY chip tester for a 286 and both built around a Harris 80C286.

If I understood it correctly, the goal behind this project seems simulating the rest of the PC (and getting mildly philosophical in the process) for the challenge and learning experience in itself?

The other project was more interested in the 286 itself, undocumented instructions, corner cases in segmentation behavior, instruction cycle timing, etc. and also trying to find out if there are any difference between the Harris and Intel variants.
