5100 STORAGE CAPACITY
The base 5100 (Model A 1) has a storage capacity of 16K (K = 1024 bytes).
Figure 4 shows how this storage
is allocated for various requirements. Notice
that the workspace available to the user (active workspace) is 10,600 bytes,
while
the remaining bytes are used for internal purposes. The storage capacity
is increased in the following models of the 5100:
Model A2 is 32K
Model A3 is 48K
Model A4 is 64K
In these models, all additional storage is allocated to the active workspace.
For example, on
the Model A4, the active workspace is approximately 60,000
bytes.
