Connecting a scsi dlt or dat drive is something i had not considered. I thought i would have had to buy and use DEC branded tape drives.
I already have a scsi dat and DLT drive in use on my SGI octane. I could probally write the image with the octane and then move the drive over to the microvax to install. Hopefully the DLT drive will be supported. the dat drive i have seems finicky at it's best. On Tue, Dec 8, 2015 at 12:44 PM, Mark G.
