Senior PROM Capabilities and Description.A Senior PROM is a firmware device designed for use exclusively in the Apple //e computers .
It replaces your standard Apple Monitor ROM(s) with a small printed circuitry board. This doubles the amount of ROM (Read Only Memory)
in your computer, without consuming a peripheral card slot (on the //e) and without losing compatibility with ANY present or future Apple //e or //c programs.
The Senior PROM provides the following functions in ROM, where they are instantly available to the computer user at any time:* A complete menu of functions available from the Reset key:

• Ability to enter the system monitor at any time to move, examine, or alter programs.
• Reboot a diskette with destroying memory.
• Copy the entire contents of memory to auxilary memory.
• Move memory from the \"language card\" to accessible memory.
• Move memory from the auxiliary card to main memory.
• Write a \"test pattern\" into memory to study disk boots.

* Enter a complete set of DOS 3.3 RWTS-based utilities:

• Initialize diskettes.
• Copy diskettes.
• Enter ROM-resident Sector Editor and Memory detective.
• Disable RWTS error-checking to diagonse disk problems.
• Alter DOS recognition bytes to examine protected software.

* Non-maskable Interrupts fully supported which allows:

• Interrupt a program, view or change memory, and restart the program.
• Capture to a DOS 3.3 disk the entire 64k of Main RAM.
• The ability to re-load and restart a captured program up to 128k from disk.
• Release software from its protected disk.
• Swap back and forth between two program (using up to 64k each) instantly.

* Enhanced monitor capabilities that include:

• ASCII display conincident with disassembly or memory display, including 65C02 support.
• Full Step and Trace functions to examine, debug and correct assembly language programs.
• A \"Mini-Assembler\" that supports the 65C02
• Full support of screen editing commands and Ctrl-S commands
• Instant return to RWTS-based menu via Ctrl-C.

Since these functions are available in ROM, they are there when you need them, and are transparent when you don\'t.
The mere push of a switch and a press of a key will make these utilities appear. Likewise, push the switch again and press a key and they disappear!
