To me, the Centurion minicomputer is more interesting than this PC clone. Strangely, the most interesting thing about the Centurion minicomputer is how uninteresting it is for an original computer system that wasn't a clone yet was on the market for ten years and had thousands of business users.

It just shows how in that era a computer company could be relatively successful selling a system that, from what I can tell, wasn't better, faster or cheaper than its competitors. It wasn't directly compatible with any other system, the OS was primitively bare bones and the software library was minimal at best. I can't find anything obviously innovative, elegant or even notable about its design or implementation. It wasn't even state of the art when first introduced and only fell further behind over the years.

It's unusual because it's pretty rare for an original, long-lived system from that era to be so uninteresting to me.
