BCU 2 compatibility to BCU 1
BCU 2 has indeed been designed to be 100 % downwards compatible to BCU 1. BCU 2 can then be running in "compatibility mode".
However, mostly one simply buys the BCU that fits to the application module and the application program that one wants to use.
This compatibility mode was nice in the beginning, when there were more application programs for BCU 1 than for BCU 2. But at tha time, BCU 2 was also remarkably more expensive than BCU 1. So, it is/was rarely done.
