DEC RX03 RT11A file extractor

List: This is the first time I've run across a bunch of double-sided 8" double-density floppies in RX02 encoding. I'm assuming that this is what's known as the RX03. The system is identified on disk as RT11A. Does anyone know of a program to extract the files from images of this sort

Hi everyone, I've been trying to figure out what is wrong with the 12V rail on my H7861 (BA11-S) power supply. It's showing about 4.2V. The 5V rail is spot on. Page 39 of the following schematics is the main part board of the PSU. http://bitsavers.org/pdf/dec/qbus/MP01233_BA11-S_schem_Mar81.pdf
