Are questions about the history of computer systems on-topic, even when there's no intent of running them now?

This site is about retrocomputing, not about computing history. But computing history is kind of inherent in retrocomputing, so… I don't know. Does it count as retrocomputing if a question is solely about a system's impact back when it was new, and not about making that system work in a modern context?

This would be a typical example (it's also on-topic where it is, on Unix & Linux; but is it on-topic here?).
