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