Comments
Starting Address 319000 319000
Used Address 39039D 39039D Currently (MRS) used memory.
End Address 3FFFFF 5FFFFF Maximum available memory.
Summary:
The amount of memory available for allocation is the difference between the End Address and the Used
Address. By familiarizing yourself with the default End Address, you will be able to easily identify if any
optional memory has or has not been installed.
Without prior knowledge of optional expansion memory chip or board installation, the only way to
determine if optional memory has been added is to perform the optional memory diagnostic or to view
the physical chip or board. For some models, viewing the physical chip or board may require disassembly
of the ECR.
