On the Vintage Computer Festival website, they document a number of builds of replica computers from the history of computer science. This gallery shows progress pics from the recreation of a DEC PDP-8, the first commercially-successful minicomputer. This is a non-working replica, BTW. To get the look of the Flip-Chip Module Arrays inside, photocopies of original modules were made and glued onto plastic card.
I started out with the basic bare frame of the replica. I used 2×2 fastened together with construction brackets. I needed to fatten the width of the vertical frame support so I glued 1/4″ thick slats onto either side. The trim edge around the top of the base is dense particle board.
Painted Frame Next to Original
The frame has been painted with a textured spraypaint that gives it a hammered metal look to match the original.
Original Cover Next to Replica
The original cover on the left was replicated using standard acrylic. The bending was done by the plastics shop where the acrylic was purchased. A groove was routed into the underside of the top piece for the main body to fit into.
