MITS Altair 680 reproduction "clone" Mini 681

I originally purchased this reproduction on eBay myself. It is in a wooden case, which I painted to display before a Vintage Computer Festival. This is per the creator:

The Mini681 is a clone of the Mits 680b with added features. This computer does everything
the 680b did but has many improvements...

Please see the eBay auction for more.
