When you say DR1 my mind goes to, for example, the 824.
When the 8x24 first came out the very first software would be called 1 or DR1. Then they improved it and called it DR2.
When the CICS came out, the very first software would be called...umm..1. Then they improved it and called it 2.
Some people try to call the CICS DR1 and DR2, but it is just how some people carry old verbage forward.
