Along the same lines, the picture in the original PDP-8 manual was of a machine that had a front panel that looked more like the PDP-5 panel than the one shipped on the 8s. Given how close the machines were in architecture, it wouldn't be surprising for a prototype. As it turns out, I saw the picture in the manual a few years before I ever saw a real straight-8. To this day, the real straight-8s look a little "wrong" to me.
