I do agree that it would be very cool to add a scaled indicator panel to your PiDP-11 and scaled RK05. You'd have to do new scaled circuit boards to be driven from the RPi and a new scaled bezel and light-shield as well as the inlay. It's all possible but I don't think I'll be doing it. You are most welcome, though, to the work I've done on any and all of those pieces if you want to take them and scale them down. If you watched the little video I posted of my early blinking lights, you probably noticed how blue those white LEDs were. I've since switched to a different LED that looks, at least to my eye, a whole lot better. In these pictures you can see a comparison. http://pdp10.froghouse.org/qsic/new-led.jpg http://pdp10.froghouse.org/qsic/new-led-2.jpg Dave
