You're right, targeting the x86 architecture added a lot of complexity without any tangible benefit. Poring over the subpar Intel documentation consumed an inordinate amount of time. That said, it only took a little over a month to build the OS itself, while the other two months I spent working on the train control program. All the equipment is notoriously flaky so coping with real-world brokenness was probably the biggest time sink.
