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 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.
I asked if the PAKS were good for older versions of VMS, like 5.5, and 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...

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.
Is it possible to use the SCSI2SD on a microPDP-11 under RT-11? I ask because
of the disk size limit under RT-11.
