I just let SIMH make it - I used a RA92 image I think.

*shrug* My UC07 can split a drive into partitions, so I went ahead and did
that.  After I split the drive I initialized the other 2GB partition and it
took about an hour and a half.

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.
This is what I was going to use the other parition on my /23+ for but I'm
waiting on getting new roms installed.
