                          by Stephane Cocquereaumont
                               & Philippe Dedieu

Installation
============

- Free the slot 1 RAM card if its merged

- Make sure that you have at least 50Kb of free RAM

- Make sure that a writeable 32Kb or 128Kb RAM card is present in slot 1

- Download the file SHELL.DIR (in binary mode)

- Check that the CRC of the directory is : #338Eh

- Go into the SHELL directory

- Launch INSTALL

The data present in port 1 will be lost, but all the data in port 0 and 
VAR will be saved.

To go back to the RPL OS, go into the RPL directory and launch RPLswitcher.

To launch SHELL again, run the STARTSHELL program.

Downloading programs under SHELL OS
===================================

The SHELL OS package contain a Xmodem protocol to transfer data between the
HP48 and a computer.

On a PC, you can use the Windows 3.1 Terminal program to transfer data
(Terminal is Windows95 compatible).

To download a program, go to the Xmodem directory, run the program called
Xrecv (Xmodem receiver), choose the program to send on the computer and 
send it with your Xmodem favorite program.

When the transfer is done, the received file is in the Xmodem directory,
you can move it with the Filer.


Notes
=====

This version is still a beta, which implies that there might remain
few bugs that will, of course, be fixed for the final version.
