You can do it pretty easily if you have an SD card reader in your PC --
what I'd do is DD the image onto the SD card starting at block zero (there
are numerous dd-like tools for windows for doing this sort of thing). Then
configure the SCSI2SD to present the first N sectors of the SD card (where
N is the number of 512-byte sectors in the CD image) as a CD-ROM, and use
the rest of the SD card for disks.

The built-in ISO burning support in Win7 is garbage, use something like
ImgBurn or the like to do the job.

I was able to expand the compressed file using 7-Zip and generate the iso
image. However, when I tried to burn the iso to a CD Win7 reported that
'The selected disk image file is not valid'. Not sure what all that means,
but anyway VMS can't handle a CD with 2048 block size so I stopped fooling
around with that. wrote:
Progress on getting the MVII up and running:
I ordered the SCSI2SD adapter and it has come in, the plan is to use it
as the system disk on the MVII.
The hobbyist VMS PAKS have arrived and I was able to download the VMS
7.3 iso, not sure what I can do with it since I think it must be burned to
a 512 byte sector CD.
Burn it to a CD. Shouldn't be anything complex here.
I asked if the PAKS were good for older versions
of VMS, like 5.5, and
Yes, I believe that is the way to proceed. Let the SCSI2SD be a couple of
drives, one for installing the software onto and another to contain the
installation CD image. At this point it is kind of a 'chicken and the egg'
thing for me, the only scsi interface I have is on the VAX. I don't have
one on the PC where the VMS image is, so I'm perplexed as to how I get the
software installation CD onto the SCSI2SD SD card. was told yes they were. We'll see about
that.
The Hobbyist VMS CD I had for VMS 7.2 was found and I was able to get
the old Toshiba CD drive to work on the MV 4000 using a CQD 223A. How can
I create an image of these CD's on the VAX 4000 that I could use in an
emulator?
I wasn't able to get the UC07 to see the CDROM because of a bad SCSI
cable, I had hoped to format the SCSI2SD using the UC07
Keep in mind that the SCSI2SD can pretend to be a CD-ROM, and can emulate
up to 4 SCSI devices at one go. No need to futz with a real drive if you
don't want to...

Is it possible to use the SCSI2SD on a
microPDP-11 under RT-11? I ask
