41CL Extra Functions
The
41CL Extra Functions
are required to provide access to the new features of the
NEWT processor that powers the 41CL calculator. Depending on your level of
experience and how adventurous you are, you may not need all of these functions.
The majority of users will only need the MMU Functions, the Turbo Functions, and the
functions that allow you to Plug and Unplug module images to and from the calculator
Ports.
If you are a HEPAX user you will need the Memory Block Functions and the Memory/IO
Read and Write Functions. Refer to the Using HEPAX section for the details of how to
do the initial setup of HEPAX memory.
Users interested in MCODE programming or building a custom module image may find
the Memory Buffer Functions useful.
The Flash Memory Functions are included for those users wishing to program the Flash
memory on the 41CL circuit board beyond the initial programming. Flash memory is non-
volatile, so it provides a convenient way to store information permanently.
The Serial Port Functions allow users to control the serial port on the 41CL circuit board.
Using the serial port will require installation of the optional serial port connector.
Advanced users interested in modifying or replacing the Operating System will need to
use the Special MMU Functions. These functions control MMU operation for the pages
of memory that contain the Operating System.
The
41CL Extra Functions
are sufficient to use most of the new features present in the
41CL, but once you are familiar with the machine, we recommend upgrading to the
41CL
Extreme Functions
. The
41CL Extreme Functions
unlock several more powerful features
of your 41CL.
