Juniper Allegro CE Owner's Manual page 83

The Memory tab allows you to adjust the allocation of RAM between
program memory and storage memory.
The majority of RAM should be allocated to program memory so that
your applications have plenty of execution space. You can figure out
how much RAM is available to use by subtracting the In Use figure
from the Allocated figure.
The Version tab displays the Allegro system version numbers and the
release date.
