- Hi Sascha,
-
- Port 0 *is* supposed to be there. It is a partitioned area of memory
- that behaves like ROM. It grows and shrinks as stuff is added to it but
- otherwise, I believe it is just like a RAM card that is *not* write
- protected. In fact, when a RAM card is MERGEd, you cannot store anything
- in the port that contains that RAM card. When you store a library in
- port 0, the actual library is stored under PORT 0 in the Library
- directory identified by its library number. The Library menu then
- contains keys which execute the library programs as well as the PORT 0
- menu label.
-
- If there are numbers stored in PORT 0, then they are probably libraries
- which, if attached, will show up in the top level of the Library menu as
- as said before.
-
- You can also store backup objects in PORT 0 by doing (2: object 1: :0:id
- STO). The backup objects can then be executed from any directory by
- typing :0:id EVAL.
-
- This explaination is as I understand it and may not be precisely correct,
- but is pretty close. Your owners manual describes this stuff in more
- detail.
-
- Hope this helps.
