Erable provides now a simplified installation procedure which
should make it a lot easier for new users.
Thanks to Mika Heiskanen and Claude-Nicolas Fiechter for letting me
modify and distribute their eqstk library and to Andre Schoorl
(ufl102) for letting me include their programs in the Erable distribution.

0/ If you want to install Erable on a RAM card in port 1, be sure that
the RAM card R/O-R/W switch enables writing.
Otherwise, if you have any libraries installed in port 0, they must be
purged. To check this type
0 PVARS
If the list at level 2 is empty, you're done.
Otherwise type DROP EVAL then
DUP DETACH PURGE
for each entry (replace PURGE by DUP RCL <name> STO PURGE if you want to keep
them).

1/ Go to the directory where you have unzipped erable.zip.

2/ Run kermit on your computer. If you don't have kermit,
you can get it at e.g.
ftp://kermit.columbia.edu
or at a mirror site. If your version of kermit does not work under Windows 95,
restart your computer in MS-DOS mode and try again.

3/ Set the line to the HP48, e.g. type
set port 2
if the HP is connected to the second serial port COM2
For Linux type
set line /dev/cua1

4/ To insure binary file transfer, type:
set file type binary

5/ Type the following command to set the speed of kermit to 9600 bauds:
set speed 9600
 
6/ Put kermit in server mode, type:
serv

7/ Now take your HP48. You must have at least 115K free in your HP48. 
If you do not have important data in your memory, press the ON key,
then the A key, then the F key and release them, then press the F key
to answer NO to Try to recover memory.
Otherwise, if you are running a stack replacement like java or eqstk, switch
to the HP48 built-in stack handler.

8/ Type the left shift key followed by the 1 key, type the B menu key to
select IOPAR, press the A menu key until line 1 looks:
IR/wire:   wire

9/ Press the alpha key, and type SETUP then the space key then KGET,
release the alpha key and press the ENTER key.
This will get the program SETUP from the computer to the HP.
If an error occurs, verify the configuration of kermit and try again.

10/ Press the VAR key, then the A menu key (for SETUP), 
this will get and install the binaries for you. If you don't have enough 
memory, an Insufficient memory error will occur. You may get a
Object in use error if you are running a stack replacement like
java or eqstk, in this case, leave them (for java, type JAVA and for eqstk,
type simultaneously ON and C).
Otherwise, after about 10 minutes your HP48 will reboot.

11/ After the reboot, press the VAR key, then the E menu key
(again for SETUP). This will continue the installation and reboot the
calculator after about 1 minute.

12/ Eventually press the VAR key, then the A menu key 
(for INIT). This will launch the modified eqstk stack
handler. Congratulations, you're done!!
