UniBone emulates now the M9312 bootstrap ROM card. Each of the 5 ROMs can be loaded with MACRO11 listings files from http://www.ak6dn.com/PDP-11/M9312/ The tricky bootvector redirection logic is also implemented. The address to execute after power-on is given as symbolic MACRO11 label. For demonstration the script "m9312+xxdp_dl0.sh" is given, which boots into 11/34 console emulator, or auto-boots XXDP from RL02. kind regards, Joerg
