Playing Reversi on Windows 1.01 IBM PC XT 5160

This is my IBM PC XT computer from the mid 1980s. It has the original 10mb hard drive, loaded with IBM PC DOS 3.10 and Windows 1.01. Here we see it boot up, test the 512 kB RAM (that's half a megabyte), and boot into DOS. I enter the date and time, as it does not have a real time clock. Then I enter WIN and it starts Windows. I use the MS-DOS Executive to start the Clock program, then the Reversi program.

The monitor is an IBM Color Display 5153, driven by an IBM Color Graphics Adaptor. Windows needs better hardware to display color, requiring an Enhanced Graphics Adapter or better, so it's in monochrome.

The mouse is an original Microsoft "Green Eye" serial mouse, with the green buttons, and bare metal ball.

This computer is very original, it has only IBM cards in it, and the case cover is still held on with the original slot/hex head screws.
