Booting a Micro PDP 11/73

A little while ago I acquired a Micro PDP 11/73. It contains 2 DEQNA cards and an Emulex CU02. I am not sure what the CU02 is, but think it is some kind of disk controller, possibly SCSI, if someone knows what it is and can point me to a manual let me know. The automatic boot is setup to boot from the DEQNA cards, however I have no idea how to set up a boot node and I am not sure what OSs the 11/73 supports. I would be happy to run RSX-11M or RSTS, I have a SIMH emulation running RSX-11M, so perhaps that can be set up as a boot node? I also have a VMS boot node, but I have no idea if I can get that to boot a PDP11. If I have to I could probably make a TK50 or TK70 tape with boot media, and I probably have the means to get an RQDX3 with a disk installed, unless I can use the CU02? In the first instance I would like to avoid this route though because I just want to verify that the machine basically works. Any suggestions? Thanks Rob
