Proposed standard for managing banked memory on the Commander X16.
This is a combination of two things:
- A mapping table that would allow a program to query the banking system to know what parts of RAM are free
- A machine language program, which would reside in ROM or RAM (based on the team's acceptance of this standard) to allocate and mark used portions of memory.
Requirements[]
- Allow marking of one or more banks of high memory as "used" or "available."
- Provide a directory of used banks by name (ie: "Editor", "Jerry's BASIC")
- Let a routine know which bank that routine is in, and provide a common mechanism for mapping common calls to a specific bank. (ie: keypress, BASIC keywords, Interrupt Service Routine)
- Should itself be easy to locate, either by use of a common name in the bank table or a tag in memory (ie: first 4 bytes of the bank are a specific sequence, such as "BMM1").
