The NVR file is optional, but the VAXone does require ka655x.bin (or 
similar) which has to be loaded first. What I have here is (comments to 
the right should NOT be included):

set console brk=10                                                makes 
Ctrl-P work
set cpu 64M
set cpu conhalt
attach nvr nvram.bin                                             see 
below
load -r ka655x.bin                                                    
load boot ROM
set rl disabled
set rq0 ra81
set rq1 ra81
set rq2 ra81
set rq3 cdrom
attach rq0 k:\vms\ra81.dsk
attach rq1 k:\vms\perf_test.vdisk
attach rq3 k:\vms\vms73.img

Then use 'boot cpu'; that should get you the console prompt.

The ka655x.bin file should come with simh.

The NVR file is optional. Just assign the name of any non-existent file.
It will be created and then the simulator will remember console stuff 
(e.g. the SET BOOT value).
