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.

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
