Hi I'm restoring a MicroPDP-11/73. I've made some initial notes here: http://www.pdp8.se/pdp1173_restore.shtml The ON/OFF rocker switch is broken. Three small plastic teeth that hold the springs in place have broken of and a forth is cracked and will soon break. I've tried three different kinds of glue without a getting a strong enough bond. I will make another attempt with a fourth kind. But, I wonder if these are available somewhere? The only marking I've found is "UND.LAB.INC.LIST" which seems to be a brand with several different kinds of rockers, some available but not the one used on this MicroPDP-11. By the looks of it, the same switch is used on MicroVAX. In the meantime I will probably take one from a spare machine. I'm borrowing a picture from the net here, but it is like the switch labled "1 0" here: https://www.codehosting.net/blog/images/pdp/frontpanel.jpg /P
