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 was told
yes they were. We'll see about that.
Yes - I have used the same PAK on 5.5 and 7.3.
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 because
of the disk size limit under RT-11.’
Yes. It works well with the later versions of RT11 V5.5-5.7. There are DU
Handlers (MSCP) that allow a large disk to be partitioned (in the handler)
into multiple drives I’ve used up to 7 in RT and 20+ in TSX+ drives at the
same time. Each drive is still limited to 32Mb per partition, but you can
manage up to 255 partitions (~8GB).

Jerry;
I am starting to read about the SCSI2SD and it will be very useful to
have it emulate multiple drives, I am thinking of one hard disk and up
to 3 CDROMs, one each for 5.5, 7.2 and 7.3. If I want to use one of the
SCSI id's for an image of a VMS installation CD do I make its size
exactly match the size of the iso image (534MB for 7.3)?
My problem is that the only computer with a SCSI interface in my
possession is the VAX (and microPDP11), so I will be forced to install
from an actual CD. This isn't that bad though, I installed 7.2 about 12
years ago on the VAX 4000 that I have.
About RT-11, I had 5.4 and it allowed you to use multiple 32MB
partitions, when I finish with the VAX I will start on the microPDP11.
I was just curious if you could use the SCSI2SD adapter with RT-11, it
looks like I can, thanks.
I am at a loss to figure out how to get data onto the SD card partitions
outside of VMS, will simh recognize the partitions?
