in honor of the IBM PC's 45th anniversary today, here is the original prototype motherboard! which side is your favorite?

a large prototyping circuit board with a grid of holes. it is covered with chips and red bypass capacitors soldered diagonally across many of the chips. you can tell it is a PC because of the 5 ISA slots and the keyboard connector.

the bottom of the board reveals a ratnest of yellow wires along with a few thicker blue and black wires, presumably for power and ground.

Where does this prototype live? CHM?
