That's normal. The Newton does garbage collection to regain unused heap only
when it has to. Be careful in not mixing up things. The 1353 Kb used on the
internal store is storage memory. A bit like the hard disk in your computer.
The 51844 free heap is like the RAM in your computer. It's a special area of
the internal memory that is reserved for applications' variables, code and
stuff like that, while the other, storage part, is for storage. When you
reset your Newton, whatever is in the heap is lost, while whatever is in the
storage area is kept.
How much free heap do you have when you reboot or reset your upgraded 2000?
You should have between 300 to 400 Kb. If Avi's Backdrop only reports 51844,
then you're not using all the heap you should on your upgraded 2000. Whether
it is not an upgraded 2000 but a plain 2000, or you're missing the latest
system patch that will let your upgraded 2000 see the additional memory.
Check the system version by doing "Memory Info" when Extras is opened. Then,
check the FAQ.
