You know, I did this recently. I started with the V9.2 tapes and
made an image with simh and then dd'd it to a zip drive (thanks eric,
good idea!) and then tried to boot it on my 11/44.
I think, however, that the simh session thought I was running on an
11/73 and when I went to run in on an 11/44, something went wrong. I
got a lot of messages complaining about the cluster size being wrong.
It didn't run rsts.
I plan to try again, telling simh i'm on a unibus machine, but I was
curious if anyone one else had see this. I told it I was using an rd31.
tiny, but big enough.
I've had good luck doing this (i.e. making an image with simh and dd-ing
it to a scsi disk) with rt11 and 211bsd. It's a quick way to bootstrap
when you have unibus hardware you (ahem) might have forgotten to remove
the battery backup jumpers from (dd11-dk) or NPR jumpers, or what other
whatnot. But it does require a unibus (or qbus) scsi card.
I could also just have a partition on the /23+ (which
also has an RLV12 in
it) with Ultrix-11 or BSD, transfer the disk images to the SCSI drive over
TCP/IP, and use 'dd' on there to copy the images over to the cartridges.
I've done that too. rcp is my friend. I did it running 2.11bsd,
however, using and 11/53 cpu in a qbus chassis. I used a kda-50 to
write an SDI disk and then moved the SDI disk to a uda-50 unibus
machine.
