As of S/N 4007360001, the RAM installed in Case Pro I+, Pro II, and Pro II+ controllers has been increased from 16 MB to 32 MB. Two 16 MB chips replace the two 8 MB chips used previously.

The increased RAM prepares the controllers for version 7.0 of the controller software, which is expected to be released this spring.

Controllers with 16 MB will be able to run version 7.0, but 32 MB is recommended for optimum performance. Two additional 8 MB RAM chips may be installed in the available slots, however, it may be more economical to replace the existing 8 MB chips with two 16 MB RAM chips, P/N 39046003, "RAM Simm 72 pin 16MB EDO".
