Chess engines and computers have come a long way over the past couple of decades. The top engines can now easily beat humans. That wasn’t always the case though. In the 80s and 90s, top grandmasters could compete with the top engines. The Boris Diplomat BD-II is a classic chess computer from Applied Concepts that can give you a fun game. It is not super strong as it is really a piece of chess computer history. It has a tiny non-sensory board on the side.
The unit lets you enter moves and change level with a bunch of buttons. Unlike Boris and Boris Master, this one has a more portable design.
